conver v2 to v3 have problem

[sexjun]

I want to convert a gitub project to v3 from v2: bypass-paywalls-chrome

and I do with cmd:

(base) ➜  extension-manifest-converter git:(main) python emc.py ../bypass-paywalls-chrome/
../bypass-paywalls-chrome/
Changing manifest_version to 3
Changing to background.service_worker in manifest.json
Changed to chrome.action in manifest.json
Changing CSP (content_security_policy) in manifest.json
Valid CSP directives for {script,object,worker}-src are {self,none,localhost,127.0.0.1}.
Converted extension into: ../bypass-paywalls-chrome/_delete

seem the results are not ok right now.
