R.effect won't work with async functions.

Trying to call an async function without "await".

My code:

extends BoxContainer

signal change_tab(new_tab: String, )

var navbar_store = R.store({ # or R.state({ ... })
	"current_tab": "menu_home", # NOTE: This needs to be the button name.
	"hide_tabs": false
})
var debounce = false


# Called when the node enters the scene tree for the first time.
func _ready():
	$"../PlayerInfo/TextureProgressBar/PlayerName".text = NakamaConnection.session.username if NakamaConnection.session else 'USERNAME'
	R.effect(_on_tab_change)
	for node in get_children():
		# BUTTONS BLACKLIST
		if !node is Button: continue
		if node.name in ['TouchArena']: continue
		node.pressed.connect(func():
			if debounce: return;
			debounce = true
			navbar_store.current_tab = node.name
			await get_tree().create_timer(.3).timeout
			debounce = false
			)
	

func _on_touch_arena_pressed():
	SceneManager.switch_scene('touch_arena')

func _on_tab_change(_ignore):
	for node in get_children():
		if !node is Button: continue
		if node.name == navbar_store.current_tab:
			node.disabled = true
			continue
		node.disabled = false
		
	debounce = true
	
	var component = await SceneManager.swap_node(
		$"../../SectionContainer".get_child(0), 
		navbar_store.current_tab, 
		true
		)
		
	if component and component.instantiated_scene:
		var component_node: Node = component.instantiated_scene
		if component_node.has_user_signal('change_tab'):
			var change_tab_array: Array = component_node.get_signal_connection_list('change_tab')
			if len(change_tab_array)>0:
				component_node.disconnect('change_tab', change_tab_array[0].callable)
			component_node.connect('change_tab', func(tab_name, hide_tabs):
				print(tab_name, hide_tabs)
				)
			
	debounce = false

If someone read this, I solved it using another func inside .effect callable to do async things
