Web Extensions support for "Add to home screen"

I can't seem to find any information anywhere on this, so I'm asking here for some clarification. Does Safari for iOS support Web Extensions when the page is added to the home screen using the "Add to home screen" share option? If so, is there a config/code requirement for the install "App" and/or extension manifest for making this work?
