Opening other applications

[ModiMan202]

Can you tell me how to open other applications that have a phone number, such as imo, max, ?

Not all applications have a direct way to open a phone number unfortunately.
I tried to check imo and max but I couldn't find one.

The app supports arbitrary intents, but you need to know them.
If you know of a link with a visible phone number that, when clicked, will open the app you want (like, for example wa.me/123456789), write it here (replace the phone number with a fake one) and I can investigate.
