2 people chopping down 1 tree

I am a beginner developer, but I guess my problem is basically this.

I want to chop down a tree and then i want another player to be able to continue chop down that same tree.
I guess it has something to do with authority but I dont really know.

Basically when the player presses the left mouse button, it tells an event that is run on server to run the multicast event, that multicast event is running the tree chopping function itself.

It works when only either server or client chops down the tree, but the other one cant interrupt and continue the process.

The tree switches actor on detected line trace.
