Trying to get a M1 Mac Mini to output via Hypertec ProDockEssential 4K to 3 screens

[Yogavenger]

Hi,

Trying to get a M1 Mac Mini to output via Hypertec ProDockEssential 4K to 3 screens.

GPU
1 x HDMI to 5K screen (fine)

For last output, USB-C to USB-C to dock then:
1 x Display port to VGA
1 x HDMI port to DVI

The two screens through the doc mirror not extend. I've installed the DisplayLink software but it says no monitor detected.

Can anyone help, pls?

Tx
