StringLike

compares a string in a request to a list of strings in your policy. The policy values can include asterisks (*) to match multiple characters and question marks (?) to match a single character. The comparison is case sensitive.

To match a request, the context key must exist in the request and must match at least one of the strings in your policy.

You can use policy variables in the value of this operator.
