CRM and Marketing Automation Stack

Hello everyone at Big Bear! I am a totally newbie and have been trying to figure out how to get Vtiger CRM and also Mautic to work with Cosmos OS - I am quite surprised to see that these apps do not exist (especially mautic as it is the #1 open source marketing automation system). Has anyone had success with this and if possible, can you share the “import compose” file that you used to create it with Cosmos OS ?

I wish there was more of a tutorial on how to find the GitHub docker image - and then tweak it so that you can make it work with Cosmos Os - it seems like for newbies like me, there is a bit of confusion on how to tweak that code…
