Using Tabular Editor to Manage Relationships in Live SSAS Connection

Hi Community,

I have Tabular Editor downloaded into the External Tools menu within Power BI Desktop and trying to modify the relationships within Tabular Editor to then update my data model for accurate filtering.  I'm trying to make changes without the help of others so that I can get a project done in a timely manner.  I make changes in Tabular Editor, but then nothing updates in my Power BI file.  I did check to allow the Power BI feature within Tabular Editor as shown in the attached.  I've also Saved any changes and tried reopening the Power BI file after the saved changes.  Could it be that it's recognizing the .bim file on my C drive?
