What kind of DP cable for Dock!?

Hi I am planning to use this docking station with my 4x2 kvm, I verified that m&kb work correctly but was wondering what kind of cable I need to go from HDMI(SOURCE) → DP(KVM), I tried two DP1.4 Cables to HDMI which I think are both unidirectional, so they didn’t work

Would something like this work? Just looking for the name of the cable that I need basically

/Displayport-Converter-BolAAzuL-Gold-Plated-Connector/dp/B07Q3VDXN8/ref=sr_1_9?keywords=hdmi%2Bto%2Bdisplayport%2Bcable&qid=1680741300&sprefix=hdmi%2Bto%2Bdiap%2Caps%2C155&sr=8-9&th=1

Thanks a bunch!

You need active adapter like this one

That cable would probably work but better to have just the adapter if you ask me
