Find rest messages that use a specific credential alias

Hey all, I am not sure if this is the correct spot for this question but I am trying to find a way to look up all of the REST messages that use a specific Credential Alias. I know that there will be several Flow actions that would have these Aliases, along with a few Outbound REST messages that are kicked off from various business rules. Is there a way to find out where these are being used? Thanks!
