figure doesn't display in Pluto upon minimal example

fig = Figure()
ga = GeoAxis(
	  fig[1, 1]; # any cell of the figure's layout
	  dest = "+proj=wintri", # the CRS in which you want to plot
	  coastlines = true # plot coastlines from Natural Earth, as a reference.
)
scatter!(ga, -120:15:120, -60:7.5:60; color = -60:7.5:60, strokecolor = (:black, 0.2))

which makie backend?

[SimonEnsemble]

your question made me ask "oh, is CairoMakie required too?"
so instead of just using GeoMakie, I'm now using GeoMakie, CairoMakie and it works.
sorry for the rookie mistake. 😞
