Documentation on RSVP Pro recaptcha field

Hi there,

could you please help and let me know, where I can find the documentation, how to activate the Recaptvcha field in a RSVP Pro template. I found the field type but just adding the field did not work out. My RSVP Pro System is spammed by a bot and every day it gets worst.

I already had to change my RSVP Pro setting to "registered users only" to prevent the heavy Spam but its not a perfect solution

I have tried to embed recaptcha into the RSVP templates, but in fact it is not showing up.
Only the field titel is shown.

I have activated the Joomla Recaptacha plugin and its working well on my contact form.

I am using latest Jevents and RSVP version on a Joomla 3.10.12 website

I hope to find a better idea soon so thanks for your kind advise.

Best regards

Michael
