Why can't I AirDrop a folder or .zip of files to iPhone's Files app?

I have files on a Mac that I want to copy via **AirDrop** to the ‘**Files**’ app on my iPhone for backup purposes. They are .html, .css, .js, and similar web formats. I do not need to modify these files on my iPhone, just archive them. I tried doing an AirDrop transfer of the whole folder, but that didn't work. Next I tried zipping the folder, but that didn't work either. What I mean specifically by "didn't work" is that after tapping Accept on the iPhone, instead of being allowed to choose a save location, I am only prompted to choose an app to open the files with. Like this: AirDrop - Open with... Cancel QuickText Update (adding screenshots):
Then... I don't want to try to open those files with QuickText. I simply want to save them to a folder. What can I do instead to accomplish the archiving of the folder (or .zip) onto the iPhone? macOS 12.6, iOS 14.8
