Filtering Security Graph API in power automate

I am using the Microsoft Graph Security connector to get alerts in Power Automate.  I am trying to filter the results to just MCAS alerts however there doesn't appear to be a field that just has MCAS that I can filter on.

I first tried filtering on "category" field which starts with MCAS and then the "vendorInformation" field that has a sub field called "provider" field that has MCAS however these don't work when using the eq operator.  Is there a "like" or "contains" option??? 

If there are no "like" or "contains" style options any suggestions on how to achieve the desired outcome?
