Webform: Hide the "add more" button

Question

I would like to get rid of the ajax "add more items" button at the bottom of a multiple elements form item.

The D8 webform I'm building has a custom composite element with multiple values allowed. The table form display has nice + and – buttons in each row. The "Add x more items" element below the table is not needed.

In the advanced tab, under "Multiple settings", there is only an option to hide the +/– buttons, not the "Add x more items" element.

Additional information:

Webform module version: 8.x-5.0-rc7

If you set the "Minimum amount of items" and "Number of empty items" to the same number the add more won't appear.

textfield:
  '#type': textfield
  '#title': textfield
  '#multiple': 5
  '#multiple__min_items': '5'
  '#multiple__empty_items': '5'

Here is the YAML source for multiple custom composite

custom_composite:
  '#type': custom_composite
  '#title': custom_composite
  '#multiple': 5
  '#multiple__min_items': '5'
  '#multiple__empty_items': '5'
  '#multiple__sorting': false
  '#multiple__operations': false
  '#element':
    textfield:
      '#type': textfield
      '#title': textfield
    select:
      '#type': select
      '#options': days
      '#title': select
