Hi  @Anju_c_v ,

Adding interactions to custom visual objects requires interaction permissions.

Start by defining a variable via options.host.hostCapabilities.allowInteractions as whether or not interaction permissions are allowed.

Try code like below:

...
   let allowInteractions = options.host.hostCapabilities.allowInteractions;
   bars.on('click', function(d) {
       if (allowInteractions) {
           selectionManager.select(d.selectionId);
           ...
       }
   });

For the ts file you provide, you can interact with the visual object in two ways, by selecting and filtering.

For more details, you can refer to below document:
