U2723QE, macOS, cannot daisy chain second U2723QE, only mirrored

Hello, I need help setting up daisychain for two U2723QE monitors with MacBook Pro M1.

Current setup:

MacBook Pro M1 TB4/ USB-C --> U2723QE USB-C to C 1.0M cable --> U2723QE #5 USB-C (Video + Data) port (Menu- Display- MST On)

U2723QE #6 DP out port --> U2723QE DP to DP 1.8M cable --> Second U2723QE #4 DP in port

With this setup, those monitors mirror each other and are not separated. When I connect Windows machine to this setup it just works. What do I need to change? Firmware on both is latest M2T105 and MTS and MMS is turned on.
