Need to set priority and have it update on screen based on custom field values

Similar but not the same as https://community.atlassian.com/t5/Jira-questions/How-to-set-Priority-based-on-custom-fields-in-behavior/qaq-p/985766

I need to find a way to automatically set the priority field of an issue based on custom impact and urgency fields that have been configured (both are single choice select lists).

Priority cannot be edited manually.

Priority must be displayed on all screens, including create, and must be updated to reflect the impact & urgency selections made.

I can set priority based on those fields using JWT and a create issue post function but:

• Editing impact and urgency is no longer possible after create.
• The create screen doesn't show the priority value as those fields are updated.

You can use ScriptRunner/Behaviours add-on. With something like this script:
