as an "Admin" I couldn't create a new project, which makes sense, however:

1- I was allowed to change the Organization Name in Settings. I suggest not giving this permission to "Admin" or anyone except the "Owner".

2- in Team Members I found a list for the Role of the "Owner", and I tested changing it to "Admin" to see what happens and it didn't work, but it makes more sense not to show the list of Roles for the "Owner" as it gives the illusion that any role can change that of the "Owner".

3- same with inviting members, it makes sense not to show the option of "Owner" in the list because an "Admin" or any other role shouldn't be able to add an "Owner".
