gmail 2fa

Good day. I need to get into my own gmail immediately or goole will delete it. I have a two-factor login set up there via SMS to a phone number that I no longer have. It doesn’t offer me other options.
Of course I know the password and the phone number.
I’m trying to install Modlishka https://github.com/drk1wi/Modlishka according to the internet instructions, but I can’t.
I need to: 1. hack it or 2. rewrite the commands for Modlishka in kali linux 2023.3 and go 1.21.4 so that I can do it myself.
I only work with public resources and it’s only for my personal needs.
