Can't import local mods

I just created a scenario and I want to publish it as a mod. I remember that there was some process for doing this in AOE2 HD Edition, but since we aren’t using stream workshop it must be different for Definitive Edition. I found where my scenario is located by opening the directory and I also found the local mods file directory. I copied and pasted my file into the local mods directory, but when I bring up the in game mods menu, clicking the import local mods button does nothing. I’m not heavily into creating mods or scenarios, so I don’t know how to make this work. Does anyone know how to publish a mod in AOE2 Definitive Edition? Do I have to rename the file or move it somewhere else? A detailed guide to this would be helpful, so I can make more scenarios in the future.
