How can I display "List of Entries" using metaobject reference in Product Description ?

[Kodamo]

Hello I have created a Product metafield definition and connected everything.

Now I want to display this in my  product description but it doesnt work.
I made some other ones with single/multi line texts and with metaobject reference and everything is working great.

Now I have chosen "List of Entries" instead of "One Entry" because my product has multiple entries.
I am using it to display the material, some products are made out of "wood" and some out of 'wood' and 'steel' for example.

When I want to add this below to my product description it doesnt show up to connect.

Any ideas?

Thank you.
