How do I get enemies for my top-down space shooter to appear and move down the screen?

I’m trying to make an arcade-like shooter-style game involving the ship moving left and right shooting enemies from above. I’ve followed many tutorials. The problem is those tutorials were made years ago and Gdevelop has changed quite a bit since then. No matter what I do, the enemies won’t show up. I’m stumped. I’m open to any suggestions at this point.

Can you give screen shots of the events that create and/or position the enemies?

You have 4 problems

1 - How to create enemies
Solution is just create object action
MAYBE add enemies to group
And you can use array to add their object names as child vars of such array
And now you could use create object from group or by name i do not remember correct name for it

2 - how to move ship
Solution would be just top down behavior and remap for topdown
You would simply set to NOTHING up and down keys while also disable default controls
And now your ship just moves left and right

3 - move enemies down
Solution i would just add PERMANENT force toward angle 90 upon creating enemies
ALTERNATIVE solution would be to give them top down behavior and just simulate key press or even platformer behavior and since there would be no platforms then gravity would do its thing

4 - when to create enemies
Solution would be same exact logic as to spawning enemies in waves
Timer and/or counter to count when to spawn next wave
