WHMCS Provisioning Add-on module isn't showing options on WHMCS

After installed the plugin, copied files to modelus folder of WHMCS install, I've activated it on both sides, addressed the whmcs remote host, but on my whmcs addon panel, when I click on WHMCS multisite provisioning, there is nothing showing....

Have I done something wrong?

My WHMCS version is 523
