How to get embedded squarespace scheduling to send events to GA4

Hi,

My website is using a scheduling block. How do I get the scheduler to send events to GA4 when someone books an appointment? 

I have set up the integration with GA4 for both my website and scheduling, following the instructions on Squarespace's support site. 

I am getting events from scheduling when someone goes directly to the scheduling url (the custom url provided by squarespace scheduling). But if someone visits my website, the embedded scheduler doesn't send any events at all.

Has anyone managed to get these events to work when using an embedded scheduler (i.e. scheduling block)? 

Thanks,

Aug
