Have you checked out this section of the help page?

There's a section on the help page about this!

Could you be more specific? What issue are you having?

Running the app as administrator should fix this!

The app doesn't have this functionality, however if you use OBS you can set your pngtuber up through there and use the virtual webcam to have it appear as your webcam in Discord or other apps! Another option is to stream the Veadotube window in Discord, if you're not streaming anything else, and that doesn't require any extra programs.
