How to use "allowedPluginIds" in "object" type PluginProperty

Hi, I was trying to filter a plugin in the property object picker list. construct.net/en/make-games/manuals/addon-sdk/reference/pluginproperty

I want to show only these two plugins in the object picker list:

So I did it like this:

new SDK.PluginProperty("object", "sdk-instance", {"allowedPluginIds":["Sparsha_FirebaseSDK"]}),

But for some reason this doesn't work : (

maybe what Sparsha meant like this

CONSTRUCT 3 (c3addon) const PLUGIN_CATEGORY = "EMI INDO", // error invalid plugin category "EMI INDO"

CONSTRUCT 2 (c2addon)

"category": "EMI INDO", // NO error

Well, no, I am not talking about PLUGIN_CATEGORY.

Its about "object" type plugin property:

It looks like the right code. It's hard to say any more than that from just this information.

What info shall I share? What can be the probable flaws? The pluginID I entered in the array is correct, no mistake there.

Is this a bug?
