Need help removing visibility of button when booking menu opened

I currently have an issue where, when I use the built in booking form, the extra button I added in which directs to Airbnb overlays over the new form. See attached photos.

What would I do to set the visibility of this button to 0 when the form is opened up?

To set visibility to hidden on load, open up the element’s properties panel and tick ‘hidden on load’.
To set display to none, tick ‘collapsed on load’.
