first of all I want to say, that you are doing a very good job. I love Opera GX so much! Thanks!
Now to my question:
I want to change the volume of the notifications of WhatsApp.
The reason is, that the notification sounds are way to loud for me. Changing it via Windows sound does not fit for me, because this would change the volume of everything else within Opera also and this is not what I want.
Thanks in advance!
