Either no sound or only a singular message sound when being called on phone (Android)

I don't know if this is also a problem with iPhone, but when I get called via Discord on my Android phone, I either don't hear any sound at all, or the same sound as a singular message. My phone is on max volume. If I go into the Discord notifications settings in my phone and to the option "Calling", I can only select the same sound options as with a text message: a singular sound. I really hope this gets fixed so that I can either hear the default Discord call sound till the caller hangs up or I answer, or that there will come an option to selevt the callsound yourself, like on normal phone calls or on Whatsapp call.
