How to list every methods/properties of an object? [duplicate]

I can’t list every keys of an object, this object is from Chrome API. I’m developing an extension and I’m using chrome API. Since chrome is an object that contains useful methods, I could just console.log(Object.keys(chrome)) on a background script and see every keys of that object.

That worked just fine, however, the logged keys are incomplete. Specifically, chrome.management have a method called getAll, but the logged result only have these keys:

Array(7)
   0: "getPermissionWarningsByManifest"
   1: "getSelf"
   2: "uninstallSelf"
   3: "ExtensionDisabledReason"
   4: "ExtensionInstallType"
   5: "ExtensionType"
   6: "LaunchType"length: 
   7[[Prototype]]: Array(0)

I don’t know where I’m doing wrong. I called the command in a right environment (background) and I’m properly logging the data. Any help would be appreciated!
