I have tried and, dude, my group will just not change from their pre-installed messaging apps, except for 2 of them. They don't care that it's more secure (arguably) or that you can pull it up on your computer (my main reason for using it), they just have no interest.
My situation is, likely, a bit different. On the familial side I required it to participate in sharing of data. Those who didn't want to use it (none) couldn't participate. Nobody really minded and when I explained why - everyone thought it made sense. I also happen to be surrounded by family who trusts each other in their respective fields and I happen to be the only one in a technical position. So, by default, my opinion has weight (good, bad or otherwise). Easy sell there and it costs all participants $0. There's about a dozen users in this group that are active.
Friends and colleagues are a different tact. I work in a space where Signal makes sense for what I do, people already get it. There are people I work with that I've incented to start using it based on Signal groups they couldn't participate in otherwise. That worked well, but bootstrapping that is the hurdle. Some didn't know what Signal was and didn't question it at all when I suggested it (probably not the best approach). Looking at my Signal "Insights" for the week and I'm at 97% encrypted messaging. The 3% is service messages being delivered via SMS and one person I've texted that I've only recently started interacting with. I've used the "I need to send you this securely" a few times, which has also worked well. In those cases, since the barrier to entry is just installing, it's rarely been met with resistance.
I'm not sure these help. I'd like to think I've trickled Signal out to hundreds of people over the years. Keep in mind when I started with this it was RedPhone/TextSecure, so it's been years. Consistency is a helpful driver.
I had some luck with a subset of friends but not all of them. A big group is still on Hangouts or whatever Google calls it now. My advice is you target 2 close friends and propose to try it out for a week. If you win them over then you can start working on more.
Software advocacy isn't easy by any means. Most people want to not shake the boat of their current habits especially since it will take effort and time to get accustomed.
I don't switch to Signal, Whatsapp, Telegram, Facebook Messenger, Discord, etc. because I have several different friend groups, family groups and people which belong to none of these groups I message with. Occasionally someone from one of the groups will try to get people to switch but the problem is none of them choose the same messaging app, so changing now puts people in the position of having to use multiple different messaging apps and remembering which they need to use for each person. It is a lot easier to stick to the common ground everyone has which in the US is your pre-installed messaging app. On the iPhone this allows you to reach everyone via either Apple's proprietary service or SMS. On Android this allows you to reach everyone via SMS or RCS. When you ask your friends to switch messaging apps you are asking them to do something which complicates their use of messaging but appears to provide no relevant benefits to them.

How close is your group? It's probably feasible to convince best friends and family to switch, but if your group contains a lot of less close friends and acquaintances, I doubt it's possible for one person to initiate a switch.
Also, it helps if you're willing to be a bit difficult, and refuse to continue to use the old app. But that only works with people who are close enough to care about communicating with you.
Yeah, the two people I have convinced to switch are my wife and someone I know who works in tech and I've known since highschool... so a very long time, lol
