SMS blocker based on keyword

[tphg]

I'd like to make a flow to block promotion SMS based on the keywords.
I used the trigger SMS received below:



Please advise the syntax I must use for "Contains Text" to add multiple keywords. May I use comma (,) to separate them?
Thanks in advance.

P/S: Have found the correct syntax for regex:
matches(sms_text,".*(keyword 1|keyword 2).*")
