django - Display admin TabularInline in list_display

Question

I have two models, which are linked reverse by foreign key from my admin point of view:

class Product(models.Model):
    name = models.CharField("name", max_length = 128)

class Store(models.Model):
    store_id = models.PositiveIntegerField(unique = True)
    product = models.ForeignKey(Product, on_delete = models.CASCADE, null = True, blank = True)

And I have an admin view where I want to display the store_id of each product it is available in list_display. I ask because I found TabularInline - my apporach:

class StoreInline(admin.TabularInline):
    model = Store
    readonly_fields = ['store_id', "product"]

@admin.register(Product)
class ProductAdmin(admin.ModelAdmin):
    list_display = ["name",]
    inlines = [StoreInline,]

But how would i be able to display the store_id value in list_displays using the Inlines method?

--- workaround (this is only a motviation for my question above), not a solution ---

I worked around by creating a custom method but, I feel like from reading (1, 2, 3) that I have solved it "by hand" and not using a path Django already has. This works:

@admin.register(Product)
class ProductAdmin(admin.ModelAdmin):
    list_display = ["name", "get_stores"]

    def get_stores(self, obj):
        return [s.store_id for s in Store.objects.filter(product = obj)]
