It should work with a Thunderbolt 3 adapter.

"In addition, it can be used to connect Thunderbolt-enabled displays — such as the Apple Thunderbolt Display and LG Thunderbolt 2 displays — to any of the Thunderbolt 3 (USB-C) / USB 4 ports on your Mac."

It should work in the other direction, too.

"As a bidirectional adapter, it can also connect new Thunderbolt 3 devices to a Mac with a Thunderbolt or Thunderbolt 2 port and macOS Sierra or later."


Be sure to use a Thunderbolt cable (Lightning bolt icon on plug). The LG display comes with two cable: one USB-C only, the other Thunderbolt 3.

That’s not correct I’m afraid, you’ll need to ask LG:
