Chrome extension managed storage policy

Hi there,

I've developed a chrome extension and now we want to deploy it using Intune. Force install of extension works great but I can't pass managed data to the extension.

Here is the scheme:

{
  "type": "object",
  "properties": {
    "apiKey": {
      "title": "API Key",
      "description": "An API key to communicate with server.",
      "type": "string"
    }
  }
}

This is the policy that I created in Intune:

OMA-URI:

./Device/Vendor/MSFT/Policy/Config/Chrome~Policy~googlechrome~3rdparty~extensions~eagefwefpbjpewefliifpgfgoewfknnmk~policy

Data type:

String

Value:

{"apiKey":"mykey123"}

But it doesn't appear in chrome://policy and when I get policies in my code with:

const result = await chrome.storage.managed.get(null);

The result is empty!

What is the problem here? And how to fix it?
