Q: How to share a folder of Notes and make them editable between users???

Hello,

I need some help...

My friend and I are apartment hunting and I have created a folder in Notes that lists each apartment we have looked at and its relevant information.  I want to be able to share this folder with my friend and let both of us have the ability to edit it.  However, I am unable to figure it out at all.  It looks like I can share each individual note, but I am unsure if it will become editable between both of us or just send them a copy.

Does anyone have any ideas for this?  Does it work in Notes or do I need to look at other apps?  If I need to look at other apps which app would be the best to accomplish this?  I feel like hat I want to accomplish is so simple.
