Sharing invite queue email issue

I have my Github account with the abbr. email address but I requested the sharing invite with the full email address. Therefore, I can’t connect my streamlit account with my GitHub account. Any solution to this particular issue? For instance, my abbr. email is {FristLetterOfFristName}{FullSurName}@xxx.xx but the full email address is {FullFristName}.{FullSurName}@xxx.xx
Many thanks for your help.
