Php version in different folder cant select different Website subdirectory

Hi, i installed different php version in virtualmin server, with php fpm, i have installed php 7.2 and php 7.4, when i go to select different php versions in Server Configuration>php version to select two different version on two different folders in my public_html folder i only see one option. In others webmin configurations in others servers (in this case i use centos 8) i see "default html directory" and empty input to put different folder and asociate to different version, in this guide you can watch this input https://www.virtualmin.com/documentation/web/multiplephp at the end. I need to configure something more? I would like to have php7.2 folder and php7.4 folder
