Multiplayer Gameplay Ability system - How call ability from widget for both client and server

Hello. Im playng with this system. Thank to some plugins I was able to work completly without C++. Im strugling with this situation. Now Im in area of inventory//items. I programed the item that way, that it contains GameplayAbility or Effect. Part of that is animation e.g. animation for use item (eating apple). When I click on item in invetory with right click, i checked if there is ability and I activate it. But I dont know how to make it for client. Widget is showed only for local player, so ability is activated only on client, its mean that the ability is which plays animation is activated only on client. What i need is also to activate ability for server version of client. Maybe some of you can help me how to solve it. Thanks.
