How to use after with multiple systems (e.g with a tuple)?

[Joel-Singh]

For context: I'm making a match 3 game

I have a layout_nodes system which is intending to control the layout of a board and match_counter entity. But layout_nodes must happen after those components have spawned in. I add my layout nodes in this line:
.add_systems(Startup, layout_nodes.after( (spawn_match_counter, spawn_board) ))

after seems like it should accept a tuple of systems, but it doesn't. Here's the error I'm getting:
rustc: required by a bound introduced by this call [E0277]
rustc: (for<'a, 'b> fn(bevy::prelude::Commands<'a, 'b>) {spawn_match_counter}, for<'a, 'b> fn(bevy::prelude::Commands<'a, 'b>) {spawn_board}) is not a system set
the trait IntoSystemSet<_> is not implemented for (for<'a, 'b> fn(bevy::prelude::Commands<'a, 'b>) {spawn_match_counter}, for<'a, 'b> fn(bevy::prelude::Commands<'a, 'b>) {spawn_board}) [E0277]

How would I actually specify a system to run after two other systems?

Here are the signatures for my functions:
fn layout_nodes( mut board: Query<Entity, With<Board>>, mut match_counter: Query<Entity, With<MatchCounter>>, mut commands: Commands ) {

fn spawn_match_counter(mut commands: Commands) {

pub fn spawn_board(mut commands: Commands) {

I realize I could chain the systems together like this:
.add_systems(Startup, ( spawn_board, spawn_match_counter, layout_nodes ).chain())
But, my spawn_board is already added to my app as it is in a "board" plugin. And the above add_systems call would result in spawn_board being called twice.

Thank you!

I found a solution: To have layout_nodes run during PostStartup. While this doesn't feel ideal, its not too bad and does work
