I don't see this Autofile button ??

이 검토는 현재 부가 기능의 이전 (1.1.7) 버전에 대한 것입니다. 

On July 7, 2021 we exchanged e-mails and on July 8 we found the issue: there was an incompatibility with an old Thunderbird extension which was not compatible with Thunderbird new API and prevented the addition of new buttons. Disabling the extension solved the issue.
