[Koha] plack with koha soruce package

Hello Friends, I am a library professional and have been using Koha in my library for the last 2 years. I have Koha 20.05.05 installed on Ubuntu 20.04. I have installed Koha using source tar package and not using koha-common installation. I have studied various koha articles to use in Koha to boost speed. But in all articles, enabling plack steps given only for koha-common installation only, using koha-plack command. In my case, I have installed Koha using tar source package, so no such commands were found. Can Anyone guide me how to enable the plack package for Koha tar source package installation. I will be thankful to you. Thanks,
