What does hamlet ask rosencrantz and guildenstern to tell the king and queen? what do the king and queen say in response?

Hamlet was disturbed about what the ghost revealed to him; thus, he wanted to verify if it is true by having a theater troop to present a play similar to it. He told Rosencrantz and Guildenstern about the play and Claudius and the queen thought that it would be good to give in to Hamlet’s request to somehow ease his grief.
