How to control Bluetooth speaker volume with my S24?

[OVERLORD24]

I've faced an issue of not being able to control volume of my Marshall bluetooth speaker via my S24 volume buttons. However, it works with my S6 Lite tablet. 

Playing around with disabling absolute volume doesn't work too, any one know how to go about this?

Edit: Nevermind, I found the solution, https://aarontechtips.com/2020/10/05/have-a-bluetooth-device-with-uncontrollable-volume-on-android-l... , here it is.
