To use Asset Server Client you must buy an Asset Server addon license. Pro + iOS Pro does not include it, it costs $500 on top of Pro to get it.
See the store page for more information.
Pro “only” gives you the Versioning System support so you can use a 3rd party versioning system. To use that go into the editor settings and enable VCS Support so the meta files are generated
