Sharing "add to calendar" info with participants

[SamanthaSQ]

Hi, 

We use Zoom to host virtual training sessions for clients who register through a separate CRM system. We create the event in Zoom and then copy the event details into our CRM, which then automatically emails the user the associated event details for the event for which they have registered. I want to include the "add to calendar information" to the automatic emails from the CRM, but cannot work out how to share that information that I am seeing in the meeting info. I can test and add to my calendar but cannot work out where to get the code to ensure it can be shared to my users. I can see similar questions asked but none have been answered for years. Thank you.
