Voice Package for Xiaomi S20+ (xiaomi.vacuum.b108gl)

Hello everyone. I am looking for a way to create a custom voice package for my Xiaomi vacuum cleaner. I tried downloading a voice package designed for Dreame vacuum cleaners, but I ended up with silence. I suspect that the file format or the archiving method is not compatible with my vacuum cleaner. Could someone provide the original voice archive or a URL link to it for the Xiaomi S20+ so I can examine it and use it as a template to create a custom version?

P.S: Previously, for Dreame vacuums, I could use a URL like https://awsde0.fds.api.xiaomi.com/dreame-product/dreame.vacuum.p2008/voices/soundpackage.json by simply changing the vacuum model. However, I don’t know how to do this for Xiaomi vacuums.
