I'm working on a Google Sheets add on. I have implemented some basic logic in https://script.google.com/ with Code.gs, index.html, appsscript.json. I deployed the project by clicking Deploy -> New Deployment. I have the deployment id. Then I open a SpreadSheet and click on Add-ons -> Get Add-ons. Basically, I don't see a way to test my private add-on by the deployment id. Are there any docs I'm missing?
