I want to see a Roundcube IMAP working installation

Before we begin, I want to see a working Roundcube installation with a test account for me to login to your webserver. I want to see the next freelancer be able to setup my system so that I can see images in the emails. I am having a problem with the embedded html coming through the emails. See the attachments. I can thoroughly explain the project in more detail, but i want to make sure that I can see a working Roundcube or do not bid. I will only award the project to someone who has experience with setting up new tailored Roundcube to my system. I am running Debian 'bullseye' on Apache2 with PHP 7.4 and have the GD and Imamagic <--maybe spelled wrong, configure to work with PHP. All green OK's I can show you my php.ini and roundcube/installer that everything is loaded but maybe having a mime problem. Might be some simple configuration that I am missing. Thank you.

Be prepared to show me a working Roundcube on your server before we get started.
