Looking at their privacy page: https://triplebyte.com/privacy
It mentions these options for deleting:

By CCPA law, they must acknowledge and comply with a deletion request within a time limit. The fines can add up very quickly per user request if they don't comply.
EDIT: Updating my post since I looked at the deletion request forms for some other sites and it seems similar. Probably try the form first and if it doesn't work, then the email.
