Increase size of ext4 partition

I have a dual boot setup with Windows 10 and Ubuntu 20.10.

I would like to use Gparted to resize the ext4 partition. It is 81% full and

lately I have been getting warnings about the partition being full and to remove

files.

I am little paranoid about doing this. So, I have requested your careful instructions.

If there is a super safe way to do this I would like to do that. All of the posts I have read

focus on using Gparted.

I have burned a Live CD of Gparted to unmount the ext4 partition which I understand is required in order to resize/ increase the size.

Here are the screenshots for review. thank you for any help.
