Active Voice Call Icon

Well, I'm pretty sure there are several proposals that are similar to this one in the past. However, I got this feature on my discord a while ago, but then it disappeared again for the second time. Therefore, I think that it might be an unintended feature. So, I would like it back as it is a very useful feature.

For those who don't know what feature am I talking about, it is a small black icon that appears on the server avatar whenever the server is having an active voice channel. It is quite similar to the icon that appears when someone is streaming in a server, but instead of the streaming icon, it is a speaker icon, similar to the green icon when you're in a voice call.

Why is this feature needed? Well, I know that you could hover on the server avatar to check if someone is in a call, but wouldn't this make everything more convenient?
