Tabs and navigation : automatic redirection

Hello !

I am recently learning how to code, and I am using this sub-tab structure on my app.
On this exemple, the welcoming view is “Home”.

Now, let’s consider the welcoming view was “About”.
When I am arrive on the welcoming view “About” and click on the “Home” tab-button, how can I be automatically redirected to the TAB 1 sub-tab? (not the parent view nesting those tabs, which is empty)

Thanks for your help!
