How to remove blacklist for extension?

Question

I have a .crx file for the chrome extension and for changing its external_extensions.json.

It works correctly, but after removing it in the user interface there is no way to reinstall it.

According to Google documentation .

If I remove the extension through the user interface, the extension will be blacklisted and

I can remove it by installing the extension through the interface and uninstalling it.

I want to know how to remove a blacklist without installing through the interface.

Is there any way to use it?

Answer 1

I'm not sure about this, but maybe if you add policies to the white list (I wonder if the black lists match, in which case whltelist overrides the black list)?

... if not, then consider using policies to install the extension next time, and they won’t be able to remove it.

Not tested.
You can try to remove your extension identifier from ExtensionInstallBlacklist.
