There doesn't appear to be a list of the arguments you can pass anywhere

The documentation of this is VERY frustrating. I was trying to find how to add
clean: true

as part of the invokation and I was only able to find it in a stackexchange arg complaining that clean: false breaks something.

Maybe, in the README, actually LIST all of the arguments?

I completely agree, and am having a similar issue trying to migrate from a system that called az webapp deploy to GitHub Actions.

It appears that all of the options are listed in
src/actionparameters.ts
for any future delvers - I'm going to operate on the assumption that these parameters largely work the same as az webapp deploy

Edit: Nope, options like target-path, clean, and restart are "Used only for OneDeploy", but it's entirely unclear what "OneDeploy" is, so yeah, not ideal.
