what type of id does tiktok accept?

ive recently been age restricted on tiktok on two accounts, i havent bothered verifying my age yet since my fyp has stayed the same and i wasnt looking at anything that would be age restricted anyway. ive come to find out that the social media ban in the UK for under 16s is coming into place soon and i dont wanna lose my account 😭 all i have in terms of ID is a young scott card which doesnt work for verifying ur age on anything. what type of ID would i need to get that tiktok would approve? i was thinking of getting a passport but i thought id ask whats best 🥹
