[Networking]How to call a command function from a UI element(a button)

I have a button that sits on my player prefab from the on click field on the button in the inspector I call a command function which I use to spawn magic attacks and stuff but it doesn't work It works as long as there is only the host in the game but as soon as a client join the game it works for niether of them I have tried all sorts of things like using bridge functions(button calls a function which is not a command which calls the command) but nothing is working I have to use button for the attack because I'm making a top-down moba style game for android which is click to move
