Custom Live steaming watermark

When live streaming from a church zoom account to Youtube the watermark shown in the bottom right hand corner is "Zoom" (see attachment) There is a way to add a custom watermark such as the Church logo (see second attachment) To do this the owner of the church zoom account must send a request to zoom - as the stake clerk I set up the zoom accounts for each ward in the stake but I'm not considered the owner who is authorised to request the change. Does anyone know who can authorise this change?

You can try mht@ChurchofJesusChrist.org, but I'm not sure if this is going to be very high priority on their rather long To Do list.
