Unable to add left edge toolbar

[gou177]

To reproduce add here:

runnerParams.callbacks.AddEdgeToolbar(HelloImGui::EdgeToolbarType::Left, []() {});

I get std::out_of_range error Found typo in source code:

if ( edgeToolbarType == EdgeToolbarType::Left)
{
    auto width = HelloImGui::EmSize(
        runnerParams.callbacks.edgesToolbars.at(EdgeToolbarType::Right).options.sizeEm);
    fullScreenSize.x = width;
}

if i replace EdgeToolbarType::Right to EdgeToolbarType::Left everything works as expected
