Load local WebExtension issue, plz help!

[hanliuxin5]

Hello everyone, when I used geckoview to load html under local assets, I tried to call the WebExtensionController.install method to load a remote or local signed xpi file.

In the callback of onInstallPrompt, I manually returned GeckoResult.allow()

The log shows that the extension was installed successfully, similar to
Extension installed: WebExtension {location=resource://android/assets/aaa.xpi, id=messaging2@example.com, flags=0},

but this flags=0 means that I cannot Call browser.runtime.connectNative("xxx")

I have already specified the required permissions when making xpi in the manifest.json

"permissions": [
    "nativeMessaging",
    "nativeMessagingFromContent",
    "geckoViewAddons",
    "<all_urls>"
  ]

The strange thing is that if I directly use the source code for making xpi, this problem will not occur.
