Hello,
As far as I know, there are two possible solutions:
- Add your application as an additional application. (pros: it’ll appear in launcher. cons: no icon or host integration.) More info, Applications and Tools | AYON Docs
- Add your application as a built-in application by extending/customizing the application addon. examples: Add BorisFX Silhouette application #45 and Add BorisFX Mocha Pro #46. Then you can create a host integration for your app.
