Layers visible on portal map

[KafilBaig]

Hi ,

I want to control the visibility of the layers in arcgis portal map based on the user privileges.

for example a user has only privilege to see point of interest layer and not street layer. 
When the webappbuilder application loads the map I want to control this . 

Is this possible to do. Please suggest.

Thanks in advance

I think you'd have to have each layer shared to specific access groups, reduced-access users will just see 'x,y,z layer could not be added to the map' on loading.
