We are using Jira Service Management 4.22.6 Datacenter version. We are using Insight to track our IT Assets including laptops, workstations, phones, etc. Now we are trying to find a way to automatically populate the assets under the leaver's name who is leaving the company, the leaver ticket was auto-triggered by the automation rule when we have something from the HR systems.
After some testing, I found a way to use Custom Field, below is the configuration on the custom field called Test-Assets:
Using this custom field, I can filter the leaver's assets, but it will only show on the issue edit page as below and only will show on the issue display page when I selected them.

I know the empty field can't be displayed on the issue display page, but how can I make it automatically show without selecting on the issue edit page like this:

Thanks.
