How to add apps to your toolbar?

Open the Onshape App Store and subscribe to the app.
Once subscribed to the app, don’t forget to grant access to the app within your user settings: https://cad.onshape.com/user/applications
Now the app should be available in the right side panel within your Onshape documents.

How to make custom apps?

Here is the best page to get started with learning to write a custom app: API Documentation

Note that app development can be much more complicated than writing custom features but if you are dedicated you can do it.
Or if you have funds, hire CADSharp to do it for you.

What is the difference between Apps and Features?

Onshape custom features are specialized modeling tools written in FeatureScript that live directly within the Part Studio toolbar and feature list, behaving exactly like native commands (such as Extrude or Fillet) to parametrically generate or modify geometry. In contrast, Onshape custom apps are external applications connected via the API that extend the platform’s ecosystem with broader capabilities—such as rendering, simulation, or CAM—typically operating in a separate tab or an integrated panel rather than functioning as a sequential step in the model’s design history.
