Capture user details on click of custom link(thumbs up or Thumbs Down) on a ticket

I have created a bot response in Zendesk using custom HTML code. In the response, I added thumbs-up 👍 and thumbs-down 👎 links for users to give quick feedback.

Was this suggestion helpful?  
<a href="https://example.com/feedback?value=up">👍 Yes</a> |  
<a href="https://example.com/feedback?value=down">👎 No</a>

Currently, I can capture the feedback value (Yes/No), but I also need to capture which user clicked on the link (for example, their Zendesk user ID or email).

Is there a way to:

1. Pass the logged-in user details automatically when they click the link?
2. Or capture this information via Zendesk API / placeholders (like {{current_user.email}}) in the link?

Any guidance or best practices would be really helpful.
