User Role WP Capabilities – Gravity Forms Webhooks not showing up

I’ve been using Ultimate Member for a number of years, but I’ve run into a conflict Gravity Forms. I’m trying to use the Gravity Forms Webhooks addon, but it won’t work because the UM user role WP permissions are not available.

According to Gravity Forms support, “gravityforms_webhooks” and “gravityforms_webhooks_uninstall” need to be enabled, but they are not included in the user roles settings.

I’m using UM version 2.3.2, and Gravity Forms version 2.6.3,
Gravity Forms User Registration Add-On version 5.0.
