When I create a project, I can create projects using Jira Work Management using a trial user premium in Jira Software (Cloud). This is really free, or I have that because they are free until 10 users? They don't appear in the "Products installed".

I ask that because I always use the hosted option and this is a new product for me (Cloud and Jira Work Management). 

And how you can see, I don't have permission to use the Jira Service Management without apply to the 3 users trial.

Thanks
