Adding resources to starting system

[-Leonidas-]

I'm trying to create a mod that adds more habitable planets and resources to the standard solar starting system in order to make it easier to play tall. While making planets habitable works just fine I can't find a way to add resources. The only tip I could find on the internet looked like this:

    planet = {
        name = "NAME_3_Juno"
        class = "pc_asteroid"
        orbit_distance = 0
        orbit_angle = 285
        size = 5
        has_ring = no
        init_effect = {
            orbital_deposit_tile = {
            clear_deposits = yes
            add_deposit = d_volatile_motes_5
            add_deposit = d_physics_5
            }
        }
    }

This however doesn't work and no resources are added. In case of planets like Jupiter, that get a random resource, just get a random resource as normal instead of the one I assigned to them. Maybe it's because the thread I found the code it in is from 2016 and the system has been changed since then. Could anyone tell me what is wrong with it or if there is another way to add resources to the starting system?

The game will delete all resources from systems that act as empire starts when it initializes them. So you can't do it with a system initializer.

Instead, you have to add the resources manually with an event after the initialization is done, hooked into (for example) the on_game_start on_action. If you add a special star flag to the system during initialization, you can find it very easily via the event system.
