How to disable the the Delete button

Django 1.11 and Python 3.6 but upgrading to Django 2.2 (slowly)

Currently I use a get_readonly_fields callable in the Admin as
documented[1]. The callable determines whether request.user is allowed
to edit the editable fields or not. This works well.

However, the readonly user can still see/use the Delete button.

The abovementioned callable doesn't make their own records readonly so
those users do need change (edit) permissions. Therefore I cannot use
permissions to solve the problem.

Can anyone suggest an approach?

Thanks

Mike
