Microsoft graph - How to patch EventSession ?

Question

Hello,

I am using Microsoft Graph to create my webinars using the POST /solutions/virtualEvents/webinars endpoint. However, when I access the EventSessions with GET /solutions/virtualEvents/webinars/{webinarId}/sessions, I see that many of the parameters do not match my expectations (attached), such as "allowAttendeeToEnableMic" for example.

My question is: how can I configure the EventSessions? I do not see a POST or PATCH method for these, nor any available settings directly from the webinar creation process.

Thank you in advance.
