Import-Module $modulePathThe module to setup an Azure Automation Hybrid Runbook Worker is included in the install directory of the Microsoft Monitoring Agent. Since install directories can change, and since this module will include a version number in the path, you cannot hard code the path into a script. Instead you can query the registry for the install path, then lookup the modules psd1 file, bypassing the need to manually check the path every time you want to onboard a hybrid worker.
