are my tiktok drafts saved to the icloud?

sooo my iphone just randomly deleted tiktok💔 probably because of all the storage that tiktok took up. in the past if i had to get a new phone, my drafts were stored in my icloud backup, so i was wondering if i reset my phone to its factory settings and set up my phone from a previous backup, will my data from third party apps ( such as tiktok) be restored to my phone? i really need to get these drafts back ( and yes i prob should have posted them earlier) but i would really like to get my drafts back if anyway possible 🥺
