Bluetooth is not working on HP 15, Ubuntu 20.04 LTS

I am using Ubuntu 20.04 LTS, My Bluetooth was working fine on Windows before, but I shifted completely to Ubuntu, and now I cant use my Bluetooth. I am new to Linux, any help in this regard will be appreciated! My hardware: RTL8821CE I have attached screenshots.
