How can i see that there is a talk notification if i miss the popup?

I only use the desktop app for communication notifications on linux and windows. I am getting pop-ups on both. I get notification sound on windows but not linux, which is a pain. but more of a pain is that i can’t figure out how to have the tray icon change colour or something that denotes there is a notification waiting.

If someone messages you, and you miss the pop-up, you need something to show that there is a message waiting like every other messaging app. A colour change or a coloured badge or icon change.

I don’t see anything like this on Windows or linux and my family and I keep missing messages.

Please advise, thx.
