How to reset and fire RigidBody3D

I began porting the game BeepSaber[1] to godot4. The game uses rigid_body.reset() and rigid_body.fire() as shown here[2] (line 669 and 700).

Both methods have been removed from godot4, is there an equivalent that I can use?

they were not removed because they never existed

they are defined in

github.com

NeoSpark314/BeepSaber/blob/master/game/BeepCube_CutFadeout.gd

extends RigidBody

onready var _meshinstance : MeshInstance = null

const timer_length = 0.3
const timer_rcp = 1.0/timer_length
var lifetime = 0.0

func _ready():
	for child in get_children():
		if child is MeshInstance:
			_meshinstance = child
			break
	if _meshinstance == null:
		print("WARN: could not find child MeshInstance")
	reset()

func reset():
	lifetime = 0.0
	visible = false
