With an arm capture they manoeuvre the craft a safe distance from the ISS then check it can hold position and move slowly toward/away. When they're satisfied then they edge it close enough to capture with the arm.
If it docks itself then you have to trust there won't be some weird last-minute f*ckup causing it to crash into the station.
