> Ranger policies support resource values with wildcards - like test*, *.txt, /finance/*.
For values that have wildcards at the beginning or at the end, which is likely to be most
common, the match can be converted into endsWith() or startsWith() - which will be more efficient
than doing a wildcard match.
