Hide one tab on tabbar in Ionic 2 app


Hello. Faced a problem: there are tabs in the application, this is the root application. I need to hide the first button so that the first page is displayed when the application is loaded. The ion-tabs element has a child element ion-tab, which in turn has the attribute show. When set to:
<ion-tab show =" false "> </ ion-tab>
the button is hidden, but when the application loads, the first “visible” tab opens. All attempts to programmatically switch to the “hidden” tab do not work. I’m waiting for help. Thank you.
