Network manager command line interface nmcli (Wireless/Wifi)

nmcli d wifi

But you can use:

nmcli -f "CHAN,BARS,SIGNAL,SSID" d wifi list ifname wlx10feed21ae1d  | sort -n

For continues scan you can combine with command "watch":

watch "nmcli -f "CHAN,BARS,SIGNAL,SSID" d wifi list ifname wlx10feed21ae1d | sort
