4-in-1 ESC powered with Power management board?

Hi sir! I have questions to ask. First i have a 4-in-1 ESC ( Dshot1200- mamba stack as pictured). What can i do to connect it to a Pixhawk 4. How can i powered the ESC because im using a 6s battery to power up my motors. Is that necessary to power up both esc and pixhawk with 2 dedicated LIPOs or i can sold my ESC to 1 of the output power of the Power Management Board. Is that enough to power all four motors of mine. The second is that is there any caution should i take when config it through mission planer app?. Or Pixhawk will recognize ESC as normal?
