Using custom roles setup to lockdown access. Gave access rights to the Forms folder and the app menu for the launchpad. However I receive the error on the GUI after clicking one of the forms to open it:
The form was not loaded due to an error.
F12 dev tools reveals 401/403 unauthorized for some api call (formbuilder/load), and also another error on the dev tools on the main Forms page (getFormDetails api call).
