We know that even though you carefully plan your presentations to go in a specific order, sometimes things change when you're actually in a Meeting.
When in a Meeting, click the "Slides" icon above the slide area to display the "Slides" panel on the left of your screen (oftentimes this panel is visible by default). You have the freedom to scroll up and down within the panel to choose the best slide for the moment (even if it's not the exact slide that you planned for during your prep).
Additionally, you have the flexibility to jump between Assets while in the middle of a Meeting. Use the "Search or Browse Content" search bar at the top of your screen to find additional Assets to use in your Meeting.
