Those are not project-specific files; they are Convai SDK files. Since this is an SDK update, some existing files may be replaced or updated during the import process.
Please make sure to back up your project before importing the updated package.
Also, please note that using the plugin requires basic Unity and C# knowledge. Topics such as package imports, file overwrites, and project backup workflows are part of basic Unity usage. If these fundamentals are unclear, we recommend reviewing Unity basics or using an AI assistant for guidance, as we may not be able to provide support for general Unity/C# setup questions.

yes i have a proper knowledge of unity, so you can not able to solve my problem of updating the sdk version from 4.1.0 to 4.2.0.
i have added from asset store and you ask me for manual importing.
you have to give me from asset store. if your latest vesrion package is there then why not shown that version for update in unity.

The latest version available on the Asset Store is **4.2.0**.
At the moment, this appears to be an issue related to Unity or your Unity account. I shared the same package with you manually. If you download it from the Asset Store, it will be the same package and the installation process will work the same way.
