How do I navigate the account setup on the SteelSeries app on keyboard?!

It’s so bloody weird, my only mouse for windows died yesterday, and I'm trying to just set up my account because I assume I can’t actually turn on the Rival 3 unless I make an account and turn it on from the app! It’s not intuitive, and right now it’s not clear how to read the privacy policy, I think I should hit tab to get over there, but it seems like it’s skipping over that entirely! This 10 minute process has now turned into 2-3 hours because people didn’t expect me to activate the new mouse with a keyboard☹️! Some help is needed, ASAP!!!!!
