Ubuntu server 18.04 auto mounting issue

We using Rock pi 4(emmc) with ubuntu server 18.04 os.
Manually mounting removable media like sd card and usb and pci ssd working fine.
But auto mounting not working.
How to enable auto mount (sd,usb,pci ssd)?

Thanks & Regards

Armbian (out of the box on desktop builds) or Google for “auto mount debian desktop ubuntu”
