I figured it after reading the previous post and here the solution.
We have Timeline Events which you can trigger to go to specific page. Please follow the following steps below :
1. Create a two pages ad with Advanced mode
2. Color the two pages to distinguish the different
3. Go to the first page, draw a div or (shape).
4. Insert a keyframe and add simple animation.
5. Move the playhead to the newly added keyframe (in this case, the last keyframe)
6. Add an Event marker by single-clicking on the diamond shape in the layer panel.
7. Go to Events panel and add event. Or you can double-click on the Event marker to bring out the Event dialog.
8. In the Event dialog, select the following:
Target: page1
Event => Timeline: event-1
Action => Google Ad: Go to page
Receiver: gwd-ad
Configuration: Page ID "page1_1" and Save
