Nit: As per our JS style guidelines I'd use 'let' here. For objects,
'const' only prohibits reassignemnt, but not modification of the
actual object.

Indentation is off here (only spaces).

A high-level comment about the UI changes:
In most places in our UI, we have a dedicated 'Remove' button right next
to the 'Add/Create' and 'Edit' button:

[Add] [Edit] [Remove]

We don't need 'Edit' here, but why not just add the button right next
to the 'Create: Directory' button?
What's the rationale of  moving the remove button to a menu on the
right-hand side?
