Login to SP2013WFE with SPSetup

From an elevated PowerShell command prompt run below command

Now you should see a long list application extension registration with the WOPIZone

To confirm type and test below command to verify that the new zone is internal-http

Change the AllowOAuthOverHttp setting in SharePoint 2013 to True. Run below command

That means we will need to allow SharePoint to allow OAuth over HTTP by running below commands

Now check one more time the status of OAuth over http

Now once again check the WOPI Zone and as you can see it is still se to internal-https

For this installation test since I had used internal and http, I am going to set the WOPI Zone accordingly as below.
