Chord diagram with 3-way ribbons

I have been making a chord diagram using this ( tutorial as a basis (thanks very much to the writer!). My issue is that I dont necesarily have just one:one matches. In some cases, I have e.g. person1:person2:person3, so Iā€™d like to have a ribbon that goes between 3+ideogram arcs. Is there any way to do this?

Thanks for any help you can provide!
