How to create an animation based on t, x, y and z data?

A bit late to the party, but I am just starting to learn Julia and came across the Lorenz attractor example in the docs. While the approach is quite intuitive and elegant, I am struggling to extend this to subplots, i.e. two trajectories of the attractor next to each other.

I have tried to push to the subplots instead of the overall plot, but as far as I understand the error message, subplots do not support the pushing of new data?

N = 200

u1 = 20*rand(3, N)
u2 = 15*ones(3, N)


plt = plot3d(
    1,
    xlim = (-30, 30),
    ylim = (-30, 30),
    zlim = (0, 60),
    title = ["Some trajectory" "Other trajectory"],
    legend = false,
    marker = 2,
    layout = (1, 2)
)

@gif for i in range(1, size(u1, 2))
    push!(plt[1], u1[:, i]...)
    push!(plt[2], u2[:, i]...)
end every 10

Giving me the following error:

MethodError: no method matching push!(::Plots.Subplot{Plots.GRBackend}, ::Float64)

Any suggestion how to achieve the wanted effect?
