When searching work itens, the user can insert a Xray JQL Function but when clicks on search gets this message:
Xray custom JQL Functions (beta) are not enabled on your Jira instance. This closed beta feature has limited availability, please reach out to Xray Support if you would like to participate.
Xray JQL Functions are by default deactivated from your instance. This means that you are able to see the functions but they are blocked, so they will not get any results.
To solve this problem: Apply to the JQL Functions Beta programme at "Request access to JQL Functions (Beta)".
You should submit the form with all the details needed for our team to activate the JQL functions on your instance.
