Cant display the SAP Odata Expand function fields

Hello Experts, I am building an app that uses the Odata modules. In a page called Requests I am showing a list of data using the Odata query Builder which looks like this: in the GetODataQuery I have a SUB_Microflow which looks like this: It works fine I dont know if I am using the expand function correctly my expand function is : $expand=Roles so in the expand action I added ‘Roles’ like this: after all this when the user clicks on an item of the list using context I display them to a different list called Approvals. The problem is I cant add the fields of my ‘Roles’ How can I add them, and is my Expand action correct? thank you in advance

I found it is a list of items so I could only do Associations to a Data List or Data Grid
