Capture specific window

[ToRRent1812]

Hi, as a twitch streamer, I would love to have twitch chat attached to my hand to quickly read what people are saying. As of now, the app can only capture desktop. Would it be possible to implement a feature, where for example, inside watch widget, I click on +, PC shows a screenshare portal, and I can choose app window to capture, then below that app, I get a cog icon to open settings for this, and inside those settings, I can choose docking method of the overlay(attached to head, to left/right controller).
