DLLNotFoundExceptionL VivoxNative MacOS AppleSilicon

We made a Unity app and the Windows version works well. But the MacOs version is works with Intel but not Apple silicon.
On both arch, you can click the launcher, access the app and login. But on server selection, the response is different for Silicon vs Intel.
Intel works good.
Silicon gives a: DLLNotFoundException: libVivoxNative
I have included the vivox bundles (3 of them: Native, sdk and another lib) in the standalone for MacOS. I have selected arch Apple Silicon + Intel.
Any idea what's going on and how to overcome this situation?
I am building the app in unity.
