No Bluetooth Found Plug in a dongle to use Bluetooth Ubuntu Budgie 20.10

About a week ago I installed Ubuntu Budgie 20.10 on my HP Pavilion 15 n004tx. I try to connect my wireless earphones (OnePlus Wireless Z earphone and Infinity Glide N120) but it says No Bluetooth Found Plug in a dongle to use Bluetooth. In Bluetooth settings I tried to click on button at top right corner but that button is inactive. I clicked on that button, but that button does not shift to the right.
