Hey guys! How can I call an registered rpc function from another server script?

Example:

1. RPC function declaration and register:

```lua
-- file1.lua

function get_value(_, _)
  return nk.json_encode({value = 42})
end

nk.register_rpc(get_value, "get_value")

```

1. Call function inside another file

```lua
-- file2.lua

function custom_rpc_func(context, payload)
  ...
  local value = nk.json_decode("-- HERE someway call the function 'get_value' and get it's response --")
  ...
end

```

Hello @Firemanarg,

What is the error you’re getting? How are you importing the function from file1 into the code in file2?

I’m not getting any error. The point is that I don’t know how to call the function in another file 😂

I haven’t found any example of this in documentation
