Discord steals focus in order to display authorisation prompt

When a third-party plugin or service requests authorisation to link to Discord (in my case, Logitech G), Discord displays a prompt to approve linking the service to Discord. On Windows 10, this prompt steals focus away from any full-screen application in the foreground.

As you can imagine, this is most unwelcome if one is in the middle of a single-player game, let alone multi-player.

This is incredibly hostile UX design.

Whilst I see the need for authorisation prompts, they should NEVER steal focus from a foreground full-screen application.
