Capacitor Plugin Fallback

I am working on a capacitor plugin.
In this plugin I already have some android and web functionality.
Currently i did not write the iOS version, however I am wondering if there is a fallback option, and if so how to use it.

For example; since I have the web functionality and I don’t have the iOS that the iOS application uses the web version?

If you don’t provide a native implementation, it should automatically fallback to the web implementation
