TikTok Account Lost After Changing Phone - No Access To Old Number Or Gmail

I had been actively using my TikTok account for about five months or more on my old iPhone XR. After switching to a new iPhone 11 Pro in March, I lost access to this account because both the phone number and the Gmail address linked to it are no longer available to me. Right now, I cannot log in to my TikTok account at all, since the usual verification methods require the old phone number or Gmail, which I cannot use anymore. Because of this, I am completely locked out of my account despite being the rightful owner. I kindly request your support in helping me recover my TikTok account by verifying my identity through alternative methods that you can offer, so that I can regain access and continue using it.
