It's a configuration from the calendly admin of the widget you're working with. Look at this documentation and you can find guidance for making the correct configuration. This forum is restricting "calendlydotcom" in the link so go to helpdotcalendlydotcom/hc/en-us/articles/223147027-Embed-options-overview
Let me know if that works out and please like and accept solution if that's helpful, thanks!
