Pb with Bonjour RATP app

I installed /e/ on an old Galaxy S4 mini to try it.
Everything works fine, bu I have an issue with the app Bonjour RATP. When I try to install it from the App Lounge, I don’t get the right app on my device, I get the RATP app instead : different app name, different icon (green not blue).
Thuus I cannot connect with my Bonjour RATP login and I cannot find the tickets I bought in te app.

Any clue ?
