API Call - List Sheet Shares

We are trying the "List Sheet Shares" (https://smartsheet.redoc.ly/tag/sheets#operation/list-sheet-shares) using PostMan as well as Microsoft Power Apps. We would like to get all the sharings of the sheets, no matter if they set on the sheet itself or inherited from the workspace. i have tried " https://api.smartsheet.com/2.0/sheets/1461969329907588/shares?sharingInclude=workspace", but I can only see the sharing from the sheet, but not from the workspace. Can you help, please?
