Battery percentage is not visible on top bar of Ubuntu 20.04 LTS for Surface Pro (Surface_Pro_1796)

I have done a fresh installation of Ubuntu 20.04 LTS on Surface Pro (Surface_Pro_1796) and it seems like there is some issue with battery percentage which supposed to be displayed on top bar of GNOME desktop. Did some research on this and tried the following without any success:

  1. I have no entry for battery under these directories /proc/acpi/battery or /sys/class/power_supply

    enter image description here

    enter image description here

  2. Ran acpi -b command – no output.

  3. Installed GNOME Tweaks and tried to enable batter percentage but it didn’t help.

    enter image description here

  4. Installed Linux Surface kernel from this link, but it didn’t help. Although it should not help, but gave a try.

I am not sure what else to try, please help.
