If you’ve created a blank project you’re not going to have the same input bindings already setup. These will need to be setup inside the project to be used.
When I test this, I did it two ways. First, I created a First Person Template project when I created a new project.
The second way, you can have your blank project, and just to to Add New in the Content Browser and select add Feature or Content pack. Then select the First Person pack. You’ll now have access to the input bindings and archviz character.
