Font issue

Hey, I’ve been using this font Noto Sans Devanagari in Canva and I’d like to use it on my blog as well. However, although when I go to Theme Options >> Typography I do get Noto Sans Devanagari in the drop down menu, it doesn’t look like the Canva font at all. Actually, the Noto Sans font has several subsets to choose from for this theme, but they all look the same. What am I doing wrong?
Thanks,
Laura
