How can I change the email signature block on meeting invitations sent through zoom?

Hi. I recently realized that when Zoom sends an invitation it has my old work company information in the signature block. It happens on my iPhone. I have my current email associated with Zoom mail, and that email account only has my personal signature block. Here's the sequence of events:

• I create a schedule meeting and save it.
• I then go to that meeting and add an attendee.
• I select the email option.
• The email is created, but the signature block contains my old information.

I've looked all over but can't find a place to change that setting. I've tried a dozen or so "solutions" that come up from a Google search, but many of them reference screens or tabs that I don't even have on my browser. (
