GLMakie: Legend for figures with two y-axis

General Usage

Hi!
I spent some time in the net but a failed to find a suitable solution.
In the forum I found the helpful topic:
https://discourse.julialang.org/t/solved-plotting-2-plots-on-same-figure-with-dual-axis/124623

But the question is still not solved:
How to specify a legend if a figure contains two y-axis.
Example:
Given are: Xvec, VectorDistValues, VectorCurrent, VectorPrivious

    fig = Figure()
    ax1 = Axis(fig[1, 1], yticklabelcolor = :blue, xlabel = "n Iterations / -", ylabel = "Cycle Counter / -")
    ax2 = Axis(fig[1, 1], yticklabelcolor = :red, yaxisposition = :right, ylabel = "Distance / -")
    
    hln1 = lines!(ax1, Xvec, VectorDistValues, label= "Distance / -")
    hln2 = lines!(ax2, Xvec, VectorCurrent,  color = :red, label= "Current")
    hln3 = lines!(ax2, Xvec, VectorPrivious, color = :orange, label= "Privious")

I know that the following works fine:

    Legend(fig[1, 2],
       [hln1, hln2, hln3],
       ["Distance / -", "Current", "Privious"],)

But I wonder if I can use the line-labels already specified in the line-definitions.
Something similar like the following (which works only for figures whith one y-axis):

    Legend(fig[1, 2], ax1)

Any ideas?
