Having a S'mores station safely

So we're still planning on having our Oct. 2020 wedding. Short Ceremony indoors, reception totally outdoors. We're having a bonfire available for S'mores, and I'm trying to think of how to have them safely. All 3 ingredients will be in separate airtight glass jars, but that does mean guests will have to touch the lids and utensils to get the stuff out. We have hand sanitizer and wipes available so people can use both. We're also considering having wooden sticks instead of a few metal ones (although its not eco-friendly, its one less thing to wipe down) but! The wooden ones would be in a pile, so it's possible people can touch multiple sticks before taking theirs, so I don't know if its better to have metal ones or the wooden ones. Should I just scrap the whole thing? It was going to be part of a dessert table of cupcakes, sugar cookies, and S'mores. So without the S'mores, we only have cupcakes and cookies. Not sure what to do??
