Is there a authentication hook available when joining a meeting

Hi,

I'm working on a solution for a health customer, and they require that each meeting member from outside their organisation to be verified through a third-party authentication mechanism upon entering the lobby of a teams meeting. This is to ensure that the person in the lobby actually is the correct person to do a health consultation with.

Is there a mechanism to redirect the user to custom authentication server either from within the lobby, or prior to entering the lobby, some sort of web hook or event?

Regards,

Pål
