Apparently Europe finally got Whatsapp to enable 3rd party chats making it easier to switch to more privacy friendly alternatives article However the only other app that currently works with it is “BirdyChat”??
Have anybody found any news about when serious alternatives will be integrated?

Again, I dont think you can access it unless you follow the rules.
I guess it’s not true public, but you can if you meet the requirements.
