I need to help with understanding if there's a difference between developing an app or an add-on for the Google Workspace Marketplace. From documentation I found that an app can only support one app for example Gmail, while the add-on can be used cross-app. Meaning also on sheets, slides, or whatever google app I choose. enter image description here https://support.google.com/marketplace/answer/172391?hl=en
Not sure what is the difference and if there's a difference.
