 * @example To retrieve details about a policy
 * ```javascript
 * // 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.
 * const input = {

 *   policyStoreId: "C7v5xMplfFH3i3e4Jrzb1a"
 * };
 * const command = new GetPolicyCommand(input);
 * const response = await client.send(command);
 * /* response is

 *   definition: {
 *     static: {
