chrome.declarativeNetRequest Callback ?

[MV3 Noob]

I have 2 related questions on MV3 chrome.declarativeNetRequest:

1. On MV2, when i was blocking a domain i could run a chrome.tabs.remove(tab.id) to remove the page as well.

On MV3 i don't know where to trigger a callback to the chrome.declarativeNetRequest

2. How do i specify to show a local html page when a rule blocks a domain ? Should i specify "redirect" instead of "block" ? or is there a method where i can keep the rule as "block" and then show a local page ?

Thanks !

You can redirect to a local html page in your extension:

• "redirect": {"extensionPath": "/close.html"} in the rule
• "web_accessible_resources": [{"resources": ["/close.html"], "matches": ["<all_urls>"]}] in manifest.json
• window.close() or chrome.tabs.getCurrent(t => chrome.tabs.remove(t.id))  in the script of this close.html page

If you want to see the URL of the blocked page in your close.html script you would need regexFilter and regexSubstitution as shown in https://stackoverflow.com/a/73392754

Thanks a lot, it the solution i was thinking but i couldn't believe that there is no callback on such an important feature. Is there any other way ?
