Recover My TikTok Account

I am writing regarding my TikTok account with the username "kasalupro1". I want to recover this old account, but I no longer have access to the phone number and email address that were previously linked to it. My main request is for the linked phone number and email on this account to be changed, so that I can regain access and secure the account again. I kindly ask you to help me verify my identity in another way and update the contact information on the account, so that I can continue using it without losing my previous content and followers.
