Topic: Precompile functions behind `@requires`

I try to add code to a module to have faster TTFX, but it seems I cannot do this for methods defined in a @required block.

module A
    using Plots
    plotlyjs()
    let
        Plots.plotlyjs_syncplot(plot(1:5))
    end
end

This gets me the error message

ERROR: LoadError: UndefVarError: plotlyjs_syncplot not defined
Stacktrace:

I get that this is most likely due to the worldage, but also using Base.invokelatest won't work for this purpose.
Is there any other way around it?
