Saving GLMakie figure without widgets

Hi,
Is there any way to save GLMakie figure without buttons/sliders?
MWE:

p = Figure(size=(500, 500))
ax = Axis(p[1, 1])
b = Button(p[2, 1], label="button", tellwidth=false)
GLMakie.scatter!(1, 1)
GLMakie.save("test.png", p)

using GLMakie.save("test.png", p[1, 1]) throws

I think there’s a colorbuffer(::Axis) method for that purpose

Thanks! It works. But it doesn’t work for Axis3

p = Figure(size=(500, 500))
ax = Axis3(p[1, 1])
b = Button(p[2, 1], label="button", tellwidth=false)
GLMakie.scatter!(1, 1, 1)
GLMakie.save("test.png", colorbuffer(ax))
