Ok in that case I wouldn't use an Approval action (or that template) at all. The steps I would use are below with screenshots further down which I hope will help you.
1. Add a choice column to your SharePoint list for Approved or Rejected
2. Create a blank flow and add a SharePoint "When a new item is created or modified" trigger. Select the site and the list.
3. Add a Get item action and select the site and the list and from Dynamic Content select ID (the item of the item that was created or modified)
4. Add a Condition control and in the left hand box select from Dynamic Content the name of the column in your SharePoint list for the Approved/Rejected (in my case it's Decision). Select is equal to in the middle box and for the right hand box click on the Expression tab on the right and enter null and select it.
5. In the green If yes channel add a "Send an email (v2)" to send you the notification that that a new request has been created and add a link to it (you'll need to click on the </> in the header area and use the html syntax in my image below.
6. In the red If no channel add another Condition control for decision is equal to Approved.
7. In the green If Yes channel add another Send an Email (v2) to let the person creating the request know that their request has been approved. In the red If no channel add another Send an Email (V2) to let them know it has been rejected.
8. When you receive the email you can click on the link to go into the item in the SharePoint list and approve or reject it and it will send the appropriate email to the requestor.
The email priority defaults to Low importance, so if you want normal or high you can change this in the advanced option on the Send an Email (V2).
If you don't want the requestor to see the Approved/Rejected choice field then you'd need to create a form in PowerApps, but that's outside the scope of this answer.
