Control access from unmanaged devices

Hi folks,

Is someone know how to limit access web browser download from unmanaged devices on Teams?

According to the following documents, I have been able to setup conditional access from unmanaged devices. That's working properly as expected on Exchange online(OWA) and SharePoint.

However, on Teams, same files, but different behavior.

-[Teams - file] - the files are restricted download.

-[Teams - post] - the post attached file CAN BE downloaded.

That would be great if someone could give me a hint to resolve this!

Thanks!
