I found that if we can use the "group": "build" property in the task - then we can use the in-built shortcut ( CTRL + SHIFT + B ) to run the task , instead of the custom keybinding. But I prefer the custom keybinding since the keys are all together.

Note that you can further use Visual Studio "Installer" Project template to create an installer and distribute your plugin. References: Short Video Long video in details (French) Autodesk Formus
