I’ve just done my plugin for my customer. I send hole plugin folder to my customer to check it. They already copy it to the plugin folder at c:\Program Files\Adobe\Adobe Photoshop 2023\Plug-ins but nothing happen. My plugin run well on my laptop via UXP development tool.
You need to package a plugin to distribute it.

Thank for your reply. I just finger out my problem in my new post: https://forums.creativeclouddeveloper.com/t/uxp-plugin-not-work-when-install-on-photoshop-2022-offline-installed-version/6857. Problem only appear when I install on my customer using Photoshop 2022 (standalone installer without creative cloud app).
