Requires MikroTik Address List Updater, make sure that both script is in system scripts and are named correctly. Copy both of the script to system scripts and make sure it is named the same as the file name (ZoomHosts and UpdateAddressList).
Run this to add the script to scheduler:

/system scheduler
add interval=1d name=updateZoomHosts on-event="/system script run ZoomHosts" policy=read,write,policy,test

For usage with simple queue, simply run:

/ip firewall mangle
add action=mark-connection chain=postrouting dst-address-list=zoom-hosts \
    new-connection-mark=zoom-connections passthrough=yes src-address=\
    192.168.1.0/24
add action=mark-packet chain=postrouting connection-mark=zoom-connections \
    new-packet-mark=zoom-packet passthrough=yes

/queue simple
add max-limit=100M/100M name="Zoom Traffic" packet-marks=zoom-packet \
    place-before=0 target=192.168.1.0/24

If used to bypass Zoom traffic, make sure to NOT set max-limit to unlimited as this will not work and packets will move to next queue.
