[Need Help] Last logged out example

Hi !
I’m having some issues executing a command for printing last-logged out for ppp secrets
I am trying to run this command but still no success.
I guess the problem is with last-logged-out parameters, but can’t figure out.

 /ppp secret print where disabled=yes && last-logged-out="may"

Any help would be appreciated.
Thanks.

Edit : Thanks to Ex1v0r I got what i wanted
/ppp secret print where disabled=yes && last-logged-out~“may”
