There are several ways you can do this.
You can head to Requests > All and filter by User to see your history of actions
You can go to your user in the Access > Users section. Once you've clicked your user, you can click to the Events tab and see a history of all the events. Sort by Action type to only see request types.
You can go to the Events section of Opal and set a filter using your desired date, actor, and event type.
Once you click on Add Filters, you can use these two input fields to see the requests you need. (NOTE: Opal doesn't require any of these form fields so you can just fill in the information you have.)
