Mobile account to pc(steam)? Help?

[rukiking23]

I've started playing on mobile first and now just downloaded the game on steam but I cant log in my account from mobile.
I launched the game on steam and the launcher automatically logs in using my steam account so tried binding the LI Pass account but it said it already was bound to another email.
I tried logging out but it just closes the launcher.
How do I connect my account from mobile to pc(steam)?
