Bases View: separate value from list with a comma

Help
1

Hi.

For my Library in Obsidian I wish to have a view that will show also the Genre of the book.

The Genre is in the property of the note formatted as list.

In the view I wish to have the various genres of the book as comma separated but I didn’t find a way to build up a formula to have this result.

I’ve tried:
join(genre, ", ")
but this doesn’t wotk,

Can you help me, please?

Thanks in advance

genre.join(", ")

Great and thanks. But (there are often a “but”), if a value (or more) of my property is a wikilink, it’s not rendered as a link but as “plain text” (brackets and Square brackets are visible).
How can this be corrected?

depeint:
  - baignoire
  - "[[∆ drapé]]"
  - debout
  - de dos
  - "[[Les Baigneuses (thème artistiques)|baigneuse]]"


Thanks in advance
