Where can I get the APP STORE URL?

Question

Python

Where can I get the APP STORE URL?
I tested the examples in the documentation, they gave the following code:

from facebookads.objects import AdSet

data = {
    AdSet.Field.name: 'My AdSet',
    AdSet.Field.bid_type: AdSet.BidType.cpc,
    AdSet.Field.bid_info: {
        'CLICKS': 500,
    },
    AdSet.Field.status: AdSet.Status.active,
    AdSet.Field.daily_budget: 2000,
    AdSet.Field.campaign_group_id: <AD_CAMPAIGN_ID>,
    AdSet.Field.promoted_object: {
        'application_id': <APP_ID>,
        'object_store_url': <APP_STORE_URL>,
    },
    AdSet.Field.targeting: {
        'geo_locations': {
            'countries': ['US','GB'],
        },
    },
}

adset = AdSet(parent_id='act_<AD_ACCOUNT_ID>')
adset.remote_create(params=data)

I found all the other IDs from the example, except for the APP STORE URL.
Can you please tell me where to find it?
