Website integration

[ContactHB]

I had got a learning online website developed few months back using zoom JWT and sdk meetings. Then there was some issue so I am thinking of upgrading it to OAuth fully as anyways, after few months, JWT and sdk will be deprecated.My question is:

Should i use OAuth or server 2 server?

Requirement is Users will register as teachers on website and they can take classes via this website on zoom.

What option should i choose?

Thanks
