How to bulk message people who favourited an item?

I have a bunch of stuff on Vinted that isn't selling, and I'm going to drop it all off at a charity shop at the end of March. Is there a way to message everyone who favourited the items to let them know in case they do want to buy anything? For example, I have one item that I listed at the end of January that has 30 favourites, so I don't even know how I would find those people to message them individually since it's been up a while.
