idk where to suggest

Not here. The Discussions header clearly says "Only post in Discussions if you CANNOT Build/Link/Run (OTHER TOPICS WILL BE DELETED)".

It exists in ImGuiIO:

// Disable default OS task bar icon flag for secondary viewports. When a viewport doesn't want a task bar icon, ImGuiViewportFlags_NoTaskBarIcon will be set on it.
bool ConfigViewportsNoTaskBarIcon;   // = false

So io.ConfigViewportsNoTaskBarIcon = false does that globally.

And setting ImGuiWindowClass::ViewportFlagsOverrideSet |= ImGuiViewportFlags_NoTaskBarIcon can be used to set it up for a single window.
