I want to stream Exit the Gungeon but I can't find where to actually stream it on this website. Can somebody help me?

This game I think could really be a good speed run game but since I'm still somewhat new to speed running I don't know how to actually create the rules for the runs. I have been trying to record myself actually beating the game but I think I might start streaming it soon, but I still don't know what to consider the start of the game and the end of it, also the beginning of a floor or an end of a floor. I'm just confused at how to start this

I want to speed run Exit the Gungeon, the sequel to Enter the Gungeon, but I can't find it here at speedrun.com. What should/can I do to get this new game here on the website? (If you want to check it out I also suggest Enter the Gungeon, I have them both and they're a lot of fun to play. You can find both on steam. Also they're a huge time killer and good to play if your bored.)
