    Examples:
        To retrieve details about a policy
        The following example retrieves information about the specified policy contained in the specified policy store. In this example, the requested policy is a template-linked policy, so it returns the ID of the policy template, and the specific principal and resource used by this policy.

        >>> client.get_policy(policy_id='9wYixMplbbZQb5fcZHyJhY', policy_store_id='C7v5xMplfFH3i3e4Jrzb1a')
        To retrieve a policy by name
        The following example retrieves information about a policy using its name instead of its ID.

        >>> client.get_policy(policy_id='name/example-policy', policy_store_id='C7v5xMplfFH3i3e4Jrzb1a')
