How to increase supergroup/group channel users limit per channel

I am using for creating channels,

payload = {
    "user_ids": [str(user_id)],
    "name": name,
    "channel_url": str(channel_url),
    "cover_url": cover_url,
    "is_super": True,
    "is_distinct": False,
    "is_public": True,
    "data": str(user_id),

I am passing this kind of payload on /v3/group_channels

The user limit I see on<app_id>/supergroup-channels/ is 2000 for all channels under members. How do I increase that or how to set it higher when I am creating the channel
