Integrate Friend app with Plaud Note (Mainly to check what's the correct path for it if there's one)

Is your feature request related to a problem? Please describe.
Plaud note has good hardware but the app lacks many features. If we integrate Friend app with Plaud note, we could help their users to get more value from AI

Describe the solution you'd like

• First we need to check if they have or not a secure Bootloader that would allow us to install a new firmware.
• Then we'd need to check if their current streaming audio characteristic (if there is one, but I think they do not stream, and transfer after using wifi ~ double check this), if we can use it, and simply pair the app to it, and receive the bluetooth bytes from it. ~ if it's possible, we should create a connection option in the app.
