Timers are nice but since you use a STATE MACHINE like setup
delta time would be even better.

var idle_time = 0

func physics_process(delta):
    match state:
        IDLE:
            if idle_time > 0:
                idle_time -= delta
            else:
                idle_time = 0
                state = NAVIGATE
    ...........
    ...........
    if navAgent.istarget_reached():
        state = IDLE
        idle_time = 3.0 # 3 seconds
