I’m not sure how it’s possible that you can’t use the SendEvent, or why it doesn’t show in the intellisense , but it’s certainly there 🙂
It can also be used with the Unity event in the inspector:

And then you can simply use the node “Events/Script/Custom Event”

Let me know a bit more info if possible on why this can’t be done in your case.
Thank you.
