Make item unable to be put into chest

Hello Mcreator community,

I recently added an item that when you right-click, it transforms into an different item for a short period of time. I also managed to make it unable to be dropped so that can't be abused. My only probblem is that you can still put the transformed item into an chest, so that it doesn't revert when you take it out again. Does anyone yet have any ideas/tutorials i could look at? If so please send them to me, that would be very appreciated!

Thanks in advance!
