Using the free trial for Power Pages and wondering how you upload your own web files to the site. If I have custom images or react files I want to use, I don't see how to include it. I have downloaded the power platform extension for Visual Studio Code and can see the yaml files but when I drag drop and do an upload command nothing is sent up. I also see the web files section and can create a web file but don't see how to include the actual file with the web file.
