Hiding "Delete" buttom into a content type on Skills and qualification page

Content

Hello there,

 

Do you know how to hide a delete button inside a content type?

This is happening into Skills and qualification page, and inside a content type once we go to edit a previously entered information, I can see the delete button. Therefore, I cannot only edit but I can delete it.

 

This creates a huge problem for those roles that should be edit this content type at most.

 

Do you know how to manage this hiding button?

 

I have tries with page composer but it seems it cannot be hide it.

Attached a screenshot to better understand.
