How to add button to GLMakie plot?

I would like to add a button to a plot made with GLMakie; it looks straightforward but I get an error:

julia> using GLMakie

How can I properly place a button?

Thank you

You need to do fig, ax, sc = scatter so that fig is actually a Figure

Thank you, it did work:

using GLMakie
xs = range(0, 10, length = 30)
ys = 0.5 .* sin.(xs)
fig = Figure()
ax = Axis(fig[1,1], title = "Example", ylabel = "Y", xlabel = "X")
sc = scatter
lines!(ax, xs, ys, linewidth = 5, color =:midnightblue)
fig[2,1] = buttongrid = GridLayout(tellwidth = false)
buttons = buttongrid[1,1] = [
    Button(fig, label = "Save Figure", fontsize = 18)
]
