How can I un-select all selections before setting new selection via api

[Anonymous]

Qlik Sense extension :

I can set new selection like this ..

self.backendApi.selectValues(dim, [value], true);  // this simply add new selection to array

But before doing that I want to clear all selections ..

self.backendApi.clearSelections();   //  tried this but its not working ..

Some how I cant clear selections ?  I just want one selection to be active
