How to hide edit button in Dashboards module home sugarcrm 9.3?

After update to  9.3 we have some error - View Render Failed, but our customization is very simple.

({
extendsFrom:'DashboardHeaderpaneView',

initialize: function(options) {
this._super("initialize", [options]);

if( app.user.get('type')!= "admin" && this.module=="Home"){
   this.meta.buttons[0].buttons = _.filter(this.meta.buttons[0].buttons, function(obj){
   return obj.name!='edit_button' && obj.name!='add_button' && obj.name!='duplicate_button';
});

this.meta.panels[0].fields = _.filter(this.meta.panels[0].fields, function(obj){
return obj.name!='my_favorite';
})
this.model.on('sync', function () {
$('.headerpane .btn-toolbar').css({'display':'none'});
$('.headerpane span[data-type="favorite"]').css({'display':'none'});
}, this);
}
}

})
