Apply compression to a mocked response - azure-api-management

Question

Is it possible to apply compression (gzip) to a mocked response? Or is it limited to the outbound section? I tried to apply mocking in the outbound section but then I would need to "skip" the entire <backend> section as there is no backend yet..
This policy below works and I get a nice sample json back, but it's not compressed.
<policies>
<inbound>
<base />
<set-header name="Content-Encoding" exists-action="override">
<value>gzip</value>
</set-header>
<mock-response status-code="200" content-type="application/json" />
</inbound>
<backend />
<outbound />
<on-error>
<base />
</on-error>
</policies>

I actually got it to work using <return-response> instead. So if anyone in the future stumbles upon this, here is the complete policy:
<policies>
<inbound>
<base />
<return-response>
<set-status code="200" reason="OK" />
<set-header name="Content-Type" exists-action="override">
<value>application/json</value>
</set-header>
<set-header name="Content-Encoding" exists-action="override">
<value>gzip</value>
</set-header>
<set-body>{
"success": true,
"data": {
"foo": [
{
"id": 1,
"bar": "xxx"
},
{
"id": 2,
"bar": "yyy"
},
{
"id": 3,
"bar": "zzz"
}
]
}
}</set-body>
</return-response>
</inbound>
<backend />
<outbound />
<on-error>
<base />
</on-error>
</policies>
