this works as in any other node implementation.
You can open channels to nodes that are available through the public internet (not Tor).
Just enter the details (e.g. you can get those also from an explorer like amboss) and open the channel for a certain amount.  

 Thanks Bumi 🙏

When opening a channel to another individual - how are they notified that someone is trying to open a channel to their node? And/or how do they “accept” the incoming connection? 

 It depends on their nodes. Typically opening channels is not disabled (bigger nodes require a minimum size often)

The two nodes communicate with each other. No human interaction is involved there.  

 Sweet, thanks - that’s very helpful 🤙
