Bigbluebutton (read carefully before bidding)

I have an online tutoring platform called geekd.live
Its a 2 way platform where tutors can create live classes and also students can request for assistance
i previously added a feature where students can request for assistance through a feature called "find a tutor" after the request is made and student makes an online payment then a zoom link generates for the live class. But now i want a bigbluebutton link to generate and not a zoom link
