Godot 4.0.3 Convert Int to String

I am converting my Godot 3 project to Godot 4 and this code no longer works...

func _ready() -> void:
	$Coins_Panel/coin_count.text = String(coins_collected)
	$Lives_Panel/lives_count.text = String(lives)

...it gives the error...

No constructor of "String" matches the signature of "String(int)".
