Wake up... the Matrix has you...
Messengers such as Snapchat and Discord are probably not a secure way to communicate. Not only do they lack a proper implementation of true end-to-end encryption, but companies and governments also implement various methods in messengers with which messages can be stored and spied on - often under the pretext of fighting terrorism and/or child pornography (in Germany, for example, this is called "chat control"). While it is important to counteract both, this approach goes too far.
Oh, you have nothing to hide? Think again! You wouldn't share your chats and photo gallery with every people, so why do you think it's a good idea to share them with governments or big corporations? This will open up spooky possibilities like the social credit system. BUT...
There are solutions!
Chose a Matrix client
For joining Matrix you need to install a Matrix client. The most popular one is probably Element but there are also many others.
Chose a Matrix server ("homeserver")
In your Matrix client of choice, you must create an account on a Matrix homeserver. There are also plenty servers to choose from (thats the whole point of having a decentralised communication plattform). You can use my homeserver or check out this list of public homeservers - you are free to use any one you like.
My Matrix homeserver is free to use and 24/7 online (I always strive for 100% availability).

Use a custom notification service (for advanced users)
I also have a UnifiedPush gateway with ntfy so you are not dependent on Firebase Cloud Messaging (Google) for push notifications: https://ntfy.cycasc.net
