Read-only field, that can carry a clickable URL and be updated by Automation

Issue Summary

Provide a field, that has ALL 3 below qualities on Issue View Screen:

1. Is Read-only
2. Renders clickable URL
3. Can be updated by Jira Automation

Research done

There are 3 field type that come close to fulfilling the requirement:

• Text field (read only) - doesn't accept markup, so URL will not be clickable
• Message Custom Field - can't be updated via Automation
• URL Field - not read-only

Workaround 1

Use an URL field and create an Automation, which would edit URL field to 

{{fieldChange.fromString}}

 after URL field has been updated by user:

Workaround 2

Using Screens, make sure you have the following configuration:

• Issue View and Issue Edit are 2 different screens
• Issue View screen has the URL field
• Issue Edit screen doesn't have URL field

With the URL field being on the View screen and not on the Edit screen, the field will be shown but not editable.

Automation will still be able to update the URL field value (tested with When: Issue created automation).
