If you have setup Automated Insights for a dataset, they will automatically be executed when the dataset is refreshed. There is nothing else to do. You do have the option of manually executing the insights, which is helpful in the situation where the dataset has been already recently refreshed, but you hadn't yet setup Automated Insights at the time of the refresh. In that case, from the Automated Insights dialog (see https://support.lityxiq.com/074862-Setting-up-Automated-Insights), simply click the button. Automated Insights will begin executing immediately. You can click the button to see if it has completed, or close the AI dialog and open the Console to watch its progress.
