Great idea! However since the repo is inactive, here's my (limited) workaround at the moment.

My method only works between a PC and an Android. It does not support multiple mobile devices.

Essentially it is a script run on a PC that can kick off the earbuds from phone and connect them to PC and vice versa.

I use Tasker and Join on Android and BluetoothConnector on my MacBook.

Here's what my script looks like...

#!/bin/bash

mac () {
    echo 'Kicking off phone'
    http -q --proxy https:socks5://127.0.0.1:1080 'https://joinjoaomgcd.appspot.com/_ah/api/messaging/v1/sendPush?apikey=?????????????????&deviceNames=???????&text=disconnect%20wi-1000xm2'
    # echo 'Conneting to mac'
    BluetoothConnector --connect FF-FF-FF-FF-FF-FF --notify
} 

phone () {
    # echo 'Kicking off mac'
    BluetoothConnector --disconnect FF-FF-FF-FF-FF-FF --notify
    echo 'Connecting to phone'
    http -q --proxy https:socks5://127.0.0.1:1080 'https://joinjoaomgcd.appspot.com/_ah/api/messaging/v1/sendPush?apikey=?????????????&deviceNames=???????&text=connect%20wi-1000xm2'
}

[ $1 == '--mac' ] && mac
[ $1 == '--phone' ] && phone

And I set up my Tasker like so.

A bit hacky but at least it works.

Hey, great contribution!!! I want a utility where I can toggle my Bluetooth earbuds connection. Let's say, when I am watching YouTube it should be using a PC<--> earbuds connection, and when I get a call on my phone, I should be able to toggle the connection to Phone <--> earbuds. does your script help in doing that? How can I set up your script so that whenever I run it, It performs the switch effortlessly?

Thanks
