When you use a Dock, sometimes you must use its outputs DIRECTLY you can generally NOT "stack" display adapters. Also docks with three HDMI ports likely need a Driver to support that dock. ¿ Did you install a driver?
The single cable you described should have worked, but there are some quirks of connecting Mac displays:
to get a Mac display to become active, you need the Mac to query the display, and the display to answer with its name and capabilities. Otherwise, the display will not be shown as present, and no data will be sent to the display.
This query is only sent at certain times:
• at startup
• at wake from sleep
• at insertion of the Mac-end of the display-cable, provided everything on that cable is ready-to-go
• on invoking Option-(Detect Display) button in Displays preferences (from another display)
so try doing some of those things and see if the display comes alive.
Modern Displays with multiple ports are sometimes busy scanning the other ports, looking for an input, and miss the query from the Mac. They need to pay attention to the port you are actually using, or they will miss the query.
Some displays have On-Screen Display settings that can be used to tell the display a computer is attached on a certain port, or a certain port should be highest priority. Changing those may make your display more responsive.
Some displays include their own private "sleep" settings for the display alone. This can allow the display to enter its own sleep mode, on top of the Mac's not sending it data. A display that is sleeping on its own cannot respond to the Mac's query, and will stay dark.

I suspect the problem is your dock. Return it and buy a dock from a 'known' brand: Elgato, Kensington, OWC, or Brydge/StonePro.
Note that even if you are able to get your dock working, it will show the same desktop on both your connected displays – your Mac supports extending the desktop to two external displays (i.e. having three separate desktops, one on your Mac and two external) but the dock only supports one extended desktop, so even though you can connect three displays they'll all show the same thing. This is common for many of the USB-C docks you find on Amazon, for example, and there's a reason those docks cost about one-third of the brands suggested above.
So sorry if a bit dim here does dock mean adaptor and one Adaptor for two screens to attach?? Would that work I have two external screens and how do I convert one of the usb-c ports to display input??
thanks and sorry if this is daft questions or I should know it 😊
tell us what you have tried already, in detail, please.
will try that tonight thanks
tried the steps recomended and it is still not recognising any display at all??
any ideas??

If you are taking the HDMI output of the Dock, and attempting to convert to convert that from HDMI to displayPort, that is likely a dead-end with no solution.
You generally need to use the Dock HDMI output directly, or convert a computer USB-C port to your display input in at most ONE adapter.
How can i connect my older monitors to my MacBook Pro 13-in 2020 ?
