Welcome to the forum!
Inkscape does not have its own font library, and uses whatever fonts are installed on the system. So if you have the font installed on Windows, you should have it in Inkscape.
If you have installed that font while Inkscape was already open, you'll need to close, and reopen Inkscape, to see it.
Do you use a font manager?
Geez, I hesitate for one minute, and Moini sneaks in again!
