/**
 * <p>Lists the virtual MFA devices defined in the Amazon Web Services account by assignment status. If
 *             you do not specify an assignment status, the operation returns a list of all virtual MFA
 *             devices. Assignment status can be <code>Assigned</code>, <code>Unassigned</code>, or
 *                 <code>Any</code>.</p>
 *         <note>
 *             <p>IAM resource-listing operations return a subset of the available
 *    attributes for the resource. For example, this operation does not return tags, even though they are an attribute of the returned object. To view all of the information for a virtual MFA device, see
 *                     <a>ListVirtualMFADevices</a>.</p>
 *         </note>
 *         <p>You can paginate the results using the <code>MaxItems</code> and <code>Marker</code>
 *             parameters.</p>

 * Use a bare-bones client and the command you need to make an API call.

 * // const { IAMClient, ListVirtualMFADevicesCommand } = require("@aws-sdk/client-iam"); // CommonJS import
 * const client = new IAMClient(config);
