Using it in a group

To use Voice Remover in a group:

1. Add @voice_remover_bot to the group as an administrator.
2. When you send the file, mention @voice_remover_bot in its caption.

Without both the admin right and the mention in the caption, the bot doesn't pick up the file. Replying to one of the bot's own messages with a file works the same way as mentioning it in the caption.
