How do I pause and continue loop in a function

I have a spawn system function that looks like this

When i pause the game, using this code

The enemy AI keeps on spawning

How can i pause the spawn system function when paused?

I would honestly just break the loop and reinstate it on button presses.

The function is 'pauzed'.

The postponed actions are not.

Use System > timescale.

(Change the rate time passes at in the game. Useful for slow-motion or pausing effects.)
