Describe the issue you are experiencing

The UI helper in the Actions section of Developer Tools is missing the option for Response Variable. This option is included in the script helper for an action.

When calling an action from Developer Tools, it seems to always push a response_variable, which means that return_reponse is True. This means that you can't test the behaviour of custom actions which have supports_response=SupportsResponse.OPTIONAL and then have different behaviour based on serviceCall.return_response.

Describe the behavior you expected

The helper in Developer Tools/Actions should be the same as the action helper in scripts etc..

Steps to reproduce the issue

1. Select Actions from Developer Tools
2. Select an Action
3. Response Variable is missing
