Documentation for business account??

I’ve been making handmade crafts and growing my following in the last year on both tiktok and instagram. For some reason my l*inktree stopped working on tiktok so I tried to make my acc private then business again and what happens??? But now I have to have a business documentation and certificate… all that just to be able to add a li*nk? Are we fr? I just use it to have my Instagram, and hopefully soon Etsy to be easy to find. But now I have to start a whole business before I’ve ever even sold anything? This is giving me a headache😭 is there anyyy way to get around this? I need my precious li*nk
