Can I connect a Bluetooth mouse to my Android phone and use it with Steam Remote Play?

[Can]

I see on the Remote Play app it has an option for "Pair Controller", would that allow me to connect a mouse and use it to control my computer via the stream? Or is it only for typical game controllers? Ty!

If I recall correctly you can use a mobile device (Like a phone, iPad, Tablet, etc) with Steam link to connect as controller input as a second player for the game.

Steam Link on Google Play:
