How to add extension to apigee-emulator on local environment?

Recently we get the need for work on the same apigee proxy more than one developer. So we are trying to use the apigee-emulator to allow us to use git as version control

We already have everything setup for VScode as it says on the documentation.

The problem is with an `extension callout we have inside one of our proxies that we need to access to salesforce. When we try to push our proxies to the apigee-emulator we get this error

If we search for the callout we can see it's the one that try to access to salesforce

How can we add this extension to be used inside the apigee-emulator?

From the error it looks like you are using Apigee Edge ExtensionCallout policy.

The vscode extension and the emulator cater towards the features available in the X and hybrid versions of Apigee. More information here

The extensions feature you are using has been replaced by the Integration callout policy.

Hope that helps
