The best you can do now for this number is using WPP the minimum possible and besides it's a google number, it was compromised since the begining. At least it's not your real phone number or a anon phone number.

Well so I did an experiment and I couldn’t see my number from my friends phone, I only don’t want people to know about my second number (google number) I’m not smart enough to understand other cons or bad opsec I just would rather not tjem find my pseudonyms
