RLS When Using Power BI Service Data Connector

We are connecting our PBI file to an existing dataset on a Premium workspace using the Power BI Service data connector (Open up Power BI Desktop>Get Data>Power BI Service). The existing dataset on the service is using Row-Level Security which uses the UserName() function in Dax. When I connect my new PBI file pointed to the service's dataset the UserName() is returning NT Authority\System. Has anyone run into this, how would I return the username of whomever is running the report? I assume since I am not logging into app.powerbi.com directly to access this dataset, it has no idea of who I am, so it's returning the System account. Anyone using this method with RLS and have a working solution?
