AWS Cron Expression – all days @ 11pm but except last day of the month

I want to write a expression which I want to execute everyday @ 11pm but except last day of the months.

Almost I tried all website I dont get answer to this – saying except last day of the month, it can be 1-30 or 1-29 or 1-28

I tried this expression in Cloudwatch Cron – but it seems it is not correct.

0 23 1-L-1 * ? *

and,

0 23 */L-1 * ? *

Thanks in advance!
