Two-Step Verification Access Issue

Due to an accident I have lost my previous android smartphone and therefore the google authenticator application that was necessary to log in to my disroot mail.
Although I can still use my email through thunderbird, I would like to regain control of my email account.
How can I get around the request for a verification code if I can’t provide it in any way?
I have in my possession the password but not the verification code. Thank you.
