We are currently facing a critical issue with the jira:workflowPostFunction module in Forge that is hindering our migration efforts from Connect to Forge.
In Connect, non-admin users with the EDIT_WORKFLOWS permission can seamlessly edit Post-Functions in Jira workflows, even if the workflow is not shared with multiple projects. However, in Forge, non-admin users are unable to invoke remotes from the Custom UI. This limitation is preventing our Forge app from connecting to our backend services, effectively breaking functionality for non-admin users.

As a developer, we would like to request an enhancement to the Forge platform that allows the jira:workflowPostFunction module to support remote invocations from the Custom UI for non-admin users, provided they have the necessary permissions (e.g., EDIT_WORKFLOWS) and the workflow is not shared across multiple projects.

Refer https://ecosystem.atlassian.net/browse/FRGE-1865 for reproducible steps.
