Accessing my shinyio account when Ive lost access to my gitlab account

Hi it's me.

I have a shinyappso account ( which I used to log into with my github account.
I changed jobs. The email registered with the github account was my old work one.
So, I've lost access to my old work email, hence lost access to my github account, hence lost access to my shinyapps account.
Maybe the easiest route from here is to sweet-talk my old employer into forwarding the github 2fa emails through to my personal email?
I guess I'll try that will I?
OK thanks,
