Customizing automated email

Hello!  I use Momence scheduling  software integrated with Zoom.  We use Zoom to offer online yoga classes, and we have the classes set up to automatically send an email with the class recording link to anyone who was registered for class.  I need to edit the automated recording message, and Momence tells me this has to be done through Zoom.  I can't find anywhere to edit the message.  Can anyone help me with some insight?  Thank you!
