Single select with belongsToMany relationship

I have a tenant system, users with teams. I want to create user and attach it to teams (team_user database), but I want to select only one team on select form because user can be in one team only, not on multiple. how can I do this correctly? 
Select::make('team')
    ->relationship('teams', 'name')
    // ->multiple() // if enable, works correctly
    ->preload(),
Select::make('team')
    ->relationship('teams', 'name')
    // ->multiple() // if enable, works correctly
    ->preload(),
Solution:
I use normal Select or relationship (without multiple) and handle manually using Lifecycle Hooks

Not best solution but maybe you can use like this; 
Select::make('team')
    ->relationship('teams', 'name')
    ->multiple()
    ->maxItems(1) // you can force to user only select one item
    ->preload(),
Select::make('team')
    ->relationship('teams', 'name')
    ->multiple()
    ->maxItems(1) // you can force to user only select one item
    ->preload(),

This prevent multi select, but UI is not great IMO
