Customize Zoom Email Invitation

Hi,

I currently have Office 365 and a Pro paid version of Zoom.

I previously customized the text in the Zoom email invitation for Meetings, but now want to update this across all users in my group.  I can't recall how to do this.

Under Admin > Account Management > Account Settings > Invitation Email Branding - the only option I'm provided is to update the email invitation for webinars.  I can't see where I can update this for Meetings.

Under Admin > Advanced > Branding - There are no options available.

I hope that someone can help.  Thank you in advance.
