Multiple "instances" open when sharing media

[Zaryu]

Describe the bug
When sharing media via other apps (like YouTube or something), a new "instance" or window, whatever you want to call it, is created, and clog up the view of open apps.

To Reproduce
Steps to reproduce the behavior:

1. Go to your app to you liking and share media, to any room
2. SchildiChat won't close the window, in which the media was shared.
3. If you repeat this a few times, there will be many windows of SchildiChat open

Expected behavior
Either close the window after sharing, or open the sharing process in the already existing windows of SchildiChat
