Ubuntu wsl on Windows 10 and Zathura

I am trying to set up zathura on Windows 10 by using Ubuntu as available from the Microsoft Store. I would like to use Zathura as my PDF viewer when writing with vim/vimtex, and am currently facing the issue:

Unable to init server: Could not connect: Connection refused (zathura:10420): Gtk-WARNING **: 15:58:19.628: cannot open display :0

This occurs when I type zathura into an Ubuntu terminal. I am new (and struggling) with Ubuntu and have only done the following:

1. I downloaded Ubuntu from the Microsoft Store.

2. I opened terminal, and typed vim. This successfully launches.

3. sudo apt update && sudo apt install zathura

4. Typing zathura produces the error mentioned above.

I've been Google searching for a few days, but I think my unfamiliarity with this technology has made difficult to spot an appropriate solution. difficult.
