Hou much is APK size for upload on Oculus Store?

hello, as you say in your publication it can be accompanied by several additional files of up to 4gb, I have a problem is that when I build my project with split binary (OBB) it generates an apk of 50MB and an OBB of 4.20GB, so I exceeded the maximum allowed by meta quest developer, how can I do so that more than one OBB is generated?

You can't "remove" the limit per se. Your build must always be smaller than 1GB, but you can upload additional expansion files to effectively increase the size of your application.

If you follow the link I've posted, it will lead you to documentation on how to create expansion files up to 4GB, depending on which platform (Unity, Unreal, Native) you use.

Specifically for Unity it leads to this page.

In case you want to go even beyond 4GB or are fine with the assets being loaded at a later time (not directly on install) streaming assets in from some cloud server at runtime is another option. How you might do this again depends on the platform you're using. For Unity you might look into their Adressables package. But really any way that downloads your required assets to local storage will work.
