after a long usage of the router, there has been a lot of session used by users and i will like to be removing using script, I have succeeded in printing all the sessions using this script, but i have been unable to remove, can someone help me out.
/tool user-manager session print where terminate-cause="lost-service"

/tool user-manager session print remove [find where terminate-cause="lost-service"]
