Allow Machine to Machine OAuth App credentials to establish Fusion Workfront Module Connections

Description - Currently, you need a username and password with System Administration access to Workfront in order to create a connection to Workfront. Would like to use an OAuth machine to machine app credentials. 

Why is this feature important to you - Most IT security offices we work with are reluctant or refuse to create a service account with username and password that isn't tied to an individual person as it's a security risk.  

How would you like the feature to work - Able to use either the Workfront OAuth Application (Workfront -> Setup) client ID/secret to create a connection, or create a Project (in developer.adobe.com) using Workfront API to generate client ID/secret, and use that in Workfront Modules to create a connection as outlined in this article https://experienceleague.adobe.com/en/docs/workfront-fusion/using/references/apps-and-their-modules/adobe-connectors/workfront-modules. 

Current Behaviour - When trying to do the following steps to use the advanced settings in the Fusion Workfront Module , we get an error and were told by Adobe Support that it's 'working as expected'
1. Can create a OAuth App in Workfront (machine to machine - https://experienceleague.adobe.com/en/docs/workfront/using/administration-and-setup/configure-integrations/manage-custom-oauth2-apps)
2. Can NOT use the Client ID and Secret to make a new Connection in a Fusion Workfront Module (https://experienceleague.adobe.com/en/docs/workfront-fusion/using/references/apps-and-their-modules/adobe-connectors/workfront-modules). ERROR after you enter the information into the connection details and click "Continue", after the Oauth window pops up, and after you enter the Workfront instance that reads "https://app.workfrontfusion.com/oauth/cb/workfront-workfront is not allowed"
