Ionic 4 switch between tabs using back button

Is this possible to switch between tabs using the back button?
Attaching gif for ref.

You can subscribe to the Back Button to do whatever you want:

this.platform.backButton.subscribeWithPriority(priority, () => {
       // Change Tab here     

Notice: You should think about a for your app fitting logic for the Priority’s you subscribe to.

I would think extremely long and hard about this, and consult with any UI experts that you trust here. I as a user would find this way out of the zone of things that I expect the back button to do.
