Update HighLevel node to support custom fields

The idea is:

The HighLevel node has a predefined set of inputs to update contacts with: Name, email, telephone. It fails to pull any custom nodes. At an absolute least it should allow us to manually input additional custom fields. The way it works in Zapier and Make is you click, “refresh” and it pulls in all available fields. We need this functionality of having the HighLevel node dynamically pull from available fields and update itself. As I think through this I guess what I’m really asking for is a LeadConnector Node. That’s the platform High Level built for this very purpose.

My use case:

I think it would be beneficial to add this because:

As it stands the HighLevel node is absolutely basic and unable to fully update records and opportunities. I fail to think of anything that warrants this basic functionality in the n8n community. The entire point of this platform is the advanced things we can accomplish, but the HighLevel node limits this to no brainer basics. Can we make this module more dynamic please?

Any resources to support this?

Are you willing to work on this?
