Importing .one file

Hi Team

I am trying to import .one file (onenote)

Without any luck, It seems that the web app or online app do not have any support for older files, please correct me if I am wrong.

Using - Windows 11 with office 365

I could not find any download for the older onenote desktop

When trying to to open the file, I receive an error - 
"This section was originally created in an older version of Onenote
To view its content, click here to download and then open the section as a local file"

No link in the massage/Error 

Thank you
