Rotate object while it's grabbed

Hi, so I’ve tried a few different things to make it so that my character can rotate objects while they’re grabbing it and moving it around the level, but so far nothing has been working for me.

Here’s what I have so far, which works fine, but I cannot for the life of me get the rotation part down :smiley: - so if someone could take a look at it, and guide me in the right direction or if someone has a youtube video on something similar, please let me know!
