Hi there. How can I change the font of my data labels to match the rest of the font? I'm using a font called "Sylfaen." It's showing up for my axis labels but I'm not sure where to specify that font for data labels. Thank you!

enrollment_by_race_ethnicity %&gt;% 
  filter(race_ethnicity == "Hispanic or Latino") %&gt;%
  ggplot(aes(x = year,
             y = percent,
             group = district)) +
  geom_line(color = "lightgray",
            alpha = 0.5) +
  geom_line(data = highlight_district,
            inherit.aes = TRUE,
            color = "blue") +
  geom_text(data = highlight_district,
            inherit.aes = TRUE,
            aes(label = percent_display),
            hjust = c(1, 0)) +
  scale_y_continuous(label = percent_format(),
                     limits =c(0,1)) +
  theme_ipsum(axis_title_size = 0,
              base_family = "Sylfaen",
              grid = "XY")
