How can i use 2 assembly with the same name in one project?

I want to work with this 2 packages

  • Lightship Map
  • Google AR Core Extension

but it keep getting this error:

Multiple precompiled assemblies with the same name Google.Protobuf.dll included on the current platform. Only one assembly with the same name is allowed per platform.
(E:/COME/Library/PackageCache/com.niantic.lightship.maps@633b3bbcda9e/Runtime/Google.Protobuf/Google.Protobuf.dll)

(E:/COME/Library/PackageCache/com.google.ar.core.arfoundation.extensions@824cb754aa71/Editor/Scripts/Internal/Analytics/Google.Protobuf.dll)

I tried to remove one of the .dll but it’s not working.
