click on your photo on the up-left and then on the key icon that says something like "security keys copy" 

 oh good christ. you mean the menu icon that says backup keys that I completely overlooked? lol thank you 

 You should’ve backed them up to a safe place when you signed up.

There’s nowhere on that app that shows your keys?
