I am adding a parameter to URL when clicking on a 'EDIT' button
    public editCustomFields() {      
      this.router.navigate(['.'], { relativeTo: this.route, queryParams: { view: 'edit' }});      
    }
Thenk the URL becomes
https://someurl.com/grids/admin/custom-fields?view=edit
But, when I manually refresh the browser, I am not able to remove those parameters from the URL. Please suggest on how can I this. Thanks.
