Is starter plan needed to use private plugin?

I have created a private plugin but my app doesn’t show up when in try “Go to test app”. I’m currently on the Free plan. Do I need to move to starter plan to use the plugin?

The plan shouldn’t affect plugin usage, just whether the app can go live or not.

Have you put your apps “id” in the test app field? When you click “Go to test app”, it will take you to whatever app id is in that field, and auto-install the testing version of that plugin
