This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/maithemewp/mai-post-previews/archive/refs/heads/master.zipUpdates itself. It ships its own updater (Plugin Update Checker), so new versions appear under Dashboard → Updates.
