Telethon how to know in advance that the user has restricted the ability to add himself to groups?

Question

Python

Good day! I need to transfer the members of my chat from one group to another, so I collect their id in an array and try to add

usersi = [321412,124124234,124124]

client(InviteToChannelRequest(
    chatid,
    usersi
))

Of course, one of them limited the ability to add themselves to groups, I would like to find out who has this restriction during the initial filtering of users from bots

participants = client.get_participants(channel_username)
usersi=[]
chatid = client.get_entity(mychat).id

for partic in client.iter_participants(channel_username):

    if partic.bot:
        print(partic.id," бот")
    elif partic.deleted:
        print(partic.id, " Удален")
    else:
        usersi.append(partic.id)
