A right click on a button can only autogenerate a page if it nows for which entity it should create a page. So Asish is right. You probably did put the widget outside of the context of an entity. You would then need a microflow to create the right object and open the correct page in the microflow.
I was facing the same issue.
So i found the solution.
Right click on button and select properties.
you will get a properties popup window. on that window you will get Events box like this
In above window you need to select “Create Object” for OnClick then click OK.
After above activity you will the option on right click on add button to select entity option.
Have you placed the button inside the dataview
If not please place it inside so you can select the entity
Ranjan, if these answers have not helped you along, can you then please add a snapshot of your entire page and the Add-button so we can see better what your current situation is?
Are you able to resolve this issue. You are correct the content of the online course is not in sync with what is showing in the tool.
