How do I remove "Add Mixmax to Gmail" from my calendar pages?

"Add Mixmax to Gmail" appears on the confirmation page when recipients confirm a meeting with you. It’s removed on our Growth and Enterprise plans, as part of our custom branding feature.  

If you’d like our help in upgrading to Growth or Enterprise, or purchasing custom branding as an add-on on top of Small Business, feel free to contact us at success@mixmax.com.
