How to show "Preview selected item" (i) button of List type field in workspace

[Mizuki3]

I'm configuring several forms of Software Asset Workspace. 

I would like to show "Preview selected item" (i) button of List type field, but I have no idea how to show the button.

I added "no_view=false" to Attributes in Dictionary Entry of a List type field and I found the button in Platform UI.

However, the button didn't appear in the form of workspace.

I would appreciate if you could tell me the way of showing the button in Workspace.

Hi @Mizuki3 

I think in List type, i icon is not work by OOTB behaviour.
