How to send an item between multiplayer

Hello. Need your help please, I need to send an object in a multiplayer game from one player to another, at the start of the game the object must be randomly assigned to a player and not to the host, , then every time the player clicks send the item must be sent to another player in a random way too. I tried many methods but I haven’t succeeded for 3 days, I don’t know Gdevelop well, can you help me please?
If possible using action, reaction if possible. Thank you very much
