event registration not showing

Hello all

When having webinars, I create an event link on LinkedIn. That link should lead to the Zoom registration page where people leave their email + name. See image below.

For some reason I don't get the link to do that. People can  jump in without registering.

In my settings I have tcked the box: "require authentication to join"

It is a recurring meeting.

I am obviously missing something or some box to tick or some setting.

is there a short video recording I could watch?

Can someone guide to what is wrong with my settings?

Thank you

Maurice
