How to add an .htaccess file to project

Hi. I'm fairly new to Bootstrap Studio and I'm planning on using Bootstrap Studio Sites to host my project. I want to remove the .html file extensions from my urls. Can anyone tell me how I should go about adding an .htaccess file to my project?

The app only supports the ".html" extension within the app. You can create and use an script on export to rename files to different extensions.
