We are looking for a JQL query that displays a list of issues updated for individuals who have made these modifications within the last 7 days. Or to have a centralized way for their users to list the tickets they worked on in JIRA in the last 7 days.

We have a specific user who has made modifications, we can utilize the updatedBy() function such as issuekey in updatedBy(XXXX, -7d) 

However, the JQL does not support the direct listing of individuals who have modified issues like issuekey in updatedBy(currentUser(), "-7d")
