Now, you can start creating Flows from within the Power Apps itself and add Power Automate as a Pane on the left hand navigation.

Let’s check out how –

Enable Power Automate Pane

In the App Studio, here’s how you can turn on the Power Automate pane –

1. In the App Studio, you can see the Settings button, clicking on which will open up the Settings area.
   Go to Upcoming Features tab and look at the Preview section since this feature is still in Preview.
   
   You’ll find the Enable Power Automate pane option turned off by default.
   
   
2. Before you turn it on, you’ll see the left hand menu doesn’t have a Power Automate icon/section added already.
   
   
3. And when you Turn it On, you’ll see the Power Automate section added.
   
   
4. Now, when you expand it, it appears like you can create a Flow from here.
   
   
5. When you click on Create new Flow, you’ll get the option to start creating from a Template or create a new one like you usually do in Power Automate app itself.
   
   
6. I clicked on Create from blank in the above step, you’ll then get the Flow editor right there and PowerApps as the trigger since this will be triggered from your Canvas Power Apps.
   
   
7. Now, you can continue to build you Flow and once done, it’ll be available in the list to be used.
   
   
8. And you can then use this Flow as per requirement.
   
   

Existing vs New Method

Let’s see the subtle difference between the existing and the new method -1

1. Once you enable this, you’ll find 2 Power Automate buttons (Perhaps this will change in the near future)
   Once will open the new pane and the other existing one will open in the old way in context of the Screen being used.
   
   
2. Additionally, the existing method will open the Power Automate portal itself in the new tab as opposed to opening the Flow in the Canvas Apps Studio itself.
   

Hope this helps!
