I haven't tried it myself, so no guarantee, but it should actually work. Connect the output of the monitor to the monitor of the third, just as you connected the first to the second.
I also had a lot of trouble with the DP-out. There are two modes that can be set. Only one of them works for me. I also had to buy a DP-HDMI adapter so that the image was displayed on my external monitor (different model).... In your case, it could also be due to a non-compatible DP cable....seems to be different standards....
The screen has a control pad on the back, with which you can control or change the OSD and also the inputs. In addition, of course, the automatic channel selection, which then switches on the picture when there is a signal via cable. Greetings
The screen charges 90W maximum power supply via USB-C. Your MacBook, if I have found the right one, charges with 100 - 240W power. It's best to do it as Kathrin said, then it wasn't for nothing.
I use only one single USB-C cable to charge and to transfer video and sound data to the monitor. The USB-C cable needs to be of good quality, that is with all circuits loaded. A simple USB-C cable which is only designed for charging purposes will not do the job.
All in all it works flawlessly like a docking station for my Mac Book
Yes, it is compatible, but I would not recommend it because the MacBook Pro has a high-resolution Retina display and a 4K UHD 3840 x 2160 pixel display fits much better externally. This monitor is also ideally suited for charging the MacBook Pro via the USB-C interface with up to 90 watts:

Since the monitor can supply the notebook with power, it is possible to work with the corresponding peripherals even with the notebook closed.
