TikTok Account Access Lost, Alternative Identity Verification Request

I have a problem accessing my old TikTok account with the username @juliaalquiza. This is the public link to the profile: https://www.tiktok.com/@juliaalquiza?_r=1&_t=ZS-9AoINJbQ14u. I lost access to both the email address and the phone number that were linked to this account, so I can no longer log in or use the normal recovery options. I did not contact TikTok support before about this issue, but now I would like to kindly request your help to reopen or restore access to this account. The account is important to me because my sister has been sending me messages there, and she became upset when I did not reply, as I could no longer access the account. I would be grateful if you could help me verify my identity in any alternative way you can offer and give me back access to the account @juliaalquiza, or provide a clear explanation of what I can do to recover it.
