The modules wagtail.core, wagtail.tests, wagtail.admin.edit_handlers and wagtail.contrib.forms.edit_handlers are removed in Wagtail 5.0.

For this reason I am being unable to continue using wagtailgmaps after the upgrade as it uses module wagtail.admin.edit_handlers.

Error:

ModuleNotFoundError: No module named 'wagtail.admin.edit_handlers'
