How to default to signup tab when opening universal login in React Native

Hi,

I mainly was using these threads as reference, as well as any linked documentation within the threads. I am using the new UL.

I’ve also tried the below and these didn’t work either.

e.g. mycompany_showsignup='1' or mycompany_initialscreen='signup'

Thanks!
