Hi pearl 

If your connect mode is direct query, you can create a paramater in power query, then set the paramater with slicer, you can refer to the following link.

The following sample cannot allow the user to input the parameter, if you want to edit the paramater to change the filter, you can only do it in power query or edit it in data source setting when the report is publised to Service, you can refer to the following link.
