How to use "exclude_line" in filebeat yml

I'm trying to exclude a specific type if lines from my logs but not sure what regex pattern I should be using. Please advise.

I want to exclude any lines that have "/ws/api/authenticate".

Example line:

255.255.255.255 [01/Mar/2022:13:16:10 -0500] "/ws/api/authenticate?licenseKey=XXXXXXXXX&product=PRODID&ipAddress=12.12.12.12&version=v20180104" - 200 0.071 [90033]
