How can I recover my Apple Account without my old phone number?

Now i cant access my apple ID linked to my artist account and cant log in to APPLE music artists. Is there any way to verify that it is indeed my account and claim it with the help of support? I can provide detailed indformation to confirm that its mine since the artist access and gmail account are still mine but due to the lost phone number that i dont even remember, i cant log in to the Apple ID account nor apple music for artists account.
