Setting up groups that can only see assigned devices.

First of all, thanks for offering such a awesome product.
I am a bit confused about something, it might simply be me who is not capable of figuring out how to set it up of course, but i was wondering if there is a way to create user groups and associate a given group of users with a set of devices.
My challange is that I need to create a "fleet" of devices, and associate them with a set of users (or a single user), the user/s should be able to login and interact with the website, but only see the devices associated with the speciifc set of users.

I was hoping something like this

fleet 1
  (usergroup)
    User1
    User2
    User3
  (devicegroup)
    Device1
    Device2
    Device3

fleet 2
  (usergroup)
    User4
    User5
    User6
  (devicegroup)
    device4
    device5
    device6

I hope this makes sense.
All the best.

ps. iv has been looking at the documentation
https://www.traccar.org/documentation/user-management/

Is the basic idea that i would register a manager as (fleet 1 manager) and then the subset of users underneath would then only see the devices associated with that manager / user setup ?

Correct. There is no concept of user group, but you can assign device groups to individual users.

Hey Anton, thanks for the quick reply, it is highly appreciated!
you can expect a ton of questions in the following days, i hope i will get most from the documentation but I'm sure that I will get somewhat confused about something :P
All the best.
