How to minimize Skype/Telegram/Viber/Slack/VK to tray on Windows 10 when you click minimize?

Question

Skype

Skype, Telegram, Viber, Slack, VK - when you click on "close" these applications are minimized to tray. Often I automatically click "minimize", which causes the taskbar to be filled, which is not very convenient (clickable): I would like to fix this little thing with some background application with a dll that would reassign the "minimize" function to click for certain applications "close". I found RBTray, but it turned out that it minimizes to tray by right-clicking on "minimize", which I don't need at all.

Answer 1

I also use RBTray, because it is very lightweight.
It comes with sources, open them, find where the input is, and change to left mouse button instead of right mouse button and close instead of minimize as an option. In general, a good enough idea, when there is a lot of RAM, to minimize everything to tray instead of closing it.
For individual applications, you can somehow do it by the title of the window.
PS In your question it is written when you click "collapse" and in addition to the question it is written when you click "close"
