What does it mean for NBA players to leave the team indefinitely?

Players are released by the team, so they don't need to participate in the team's confrontation practice match, and it is impossible to play. The team sends individual physical fitness or special coaches to accompany them to train outside the team to recover or maintain their state. At the same time, the team actively contacted other teams to discuss the trading plan. Once the deal is made, the players immediately pack their bags and leave the team!
