How can I check for a value in a Collection Variable to filter by it?

Hi Everyone! 

I'm trying to figure out a way to check for a value in a collection variable. For example: Lets say I have a Flow that triggers on creation of an Opportunity, but I want to filter it to only fire on 3 record types WITHOUT hard coding any record type IDs in the filter criteria. Is there a way to do that?   I was able to use Get Records to pull a list of Record Type IDs, but I don't know how to check in Flow if the current triggering record is a part of this collection.   Thanks in advance for any assistance!
