Can you publish this as a package via https://openupm.com/? Instructions can be found here: https://openupm.com/docs/adding-upm-package.html#upm-package-criteria Currently, a package with this name already exists, but it looks like it's a fork with some modifications. https://openupm.com/packages/com.bunny83.simplejson/ Also, unfortunately, that specific bundle doesn't even work :(
