const database = new Map();

world.afterEvents.entityHitEntity.subscribe(({ hitEntity, damagingEntity: entity }) => {
    const health = hitEntity.getComponent("minecraft:health");
    const mobs = ['minecraft:cow'];
    if (health.currentValue > 0 || !mobs.includes(hitEntity.typeId)) return;
    const entityData = (database.get(entity.name) ?? []);
    if (!entityData.includes(hitEntity.typeId)) {
        entityData.push(hitEntity.typeId);
        database.set(entity.name, entityData);
    }
});

function PlayersMenu(player) {
    const data = database.get(player.name) ?? [];
    const form = new ActionFormData();
    form.title('Something');
    form.body('Select an entity:');

    form.button('Back');

    for (const entityId of data) {
form.button(entityId.replace('minecraft:', ''));
    }

    form.show(player).then((r) => {
        if (r.canceled) return;
        const response = r.selection;
        switch (response) {
            case 0:
                StatisticsMenu(player);
                break;
            default:
        }
    })
}

I want to make the buttons created using "for" into a "dynamic property" so that the buttons are not deleted after exiting the world.
