When creating an "extra" email provider through the app marketplace, we can send 1-1 emails through the contact/conversation UI (very cool), but we're not able yet to send bulk emails by selecting multiple contacts in the list and choosing the secondary provider.

According to the docs located here (https://marketplace.gohighlevel.com/docs/marketplace-modules/ConversationProviders), "Bulk Actions - Only supported on default providers at this time."

We have a use case where we need to expand this to the new extra provider.
