I can not mark output packets from calea in mangle

I have a ip firewall calea rule that catch traffic. I want to mark this output traffic for priorize in queue tree, but I can’t, counters are always 0

My mangle rule is:
/ip firewall mangle add action=mark-packet chain=output comment=Calea disabled=no new-packet-mark=calea passthrough=no port=5555 protocol=udp

and my calea rule:
/ip firewall calea add action=sniff-pc chain=forward connection-bytes=0-1492 disabled=no dst-address=!10.0.0.0/16 packet-size=90-2048 protocol=tcp sniff-id=105 sniff-target=XXX.XXX.XXX.XXX sniff-target-port=5555 src-address=10.0.0.0/16

where XXX.XXX.XXX.XXX is a server in the cloud.
I try ‘output’ and ‘forward’ chain…
Is not ip firewall mangle valid to mark calea traffic??

Thanks

Please,
