How to get a user's Requester/User ID to use in Copilot Studio

Hi,

I am trying to experiment with creating a Copilot within Copilot Studio that can create a FreshService support ticket based on the information provided by the user. The information from the Copilot would be passed a Connector Action using the FreshService Connector’s Create a ticket (V2) action. The most of the fields are easy enough to automatically fill in with variables gathered earlier or set them manually.

However, the snag I’ve hit is that the Create a ticket action has Requester Id as a mandatory number field. I imagine most (if not all) users who would want to create a support ticket via this way wouldn’t know their FreshService User-id. Is there a way I can use the information they provide (either full name or email?) to get their User-id from FreshService? Or is there an alternative I could use?

Apologises if this is potentially a simple solution. Fairly new to automations, APIs ect.

Thank you in advance!
