Confused about authorization token expiring

API
5

The response that comes from an Implicit doesn’t come with “expires_in”

http://localhost:3000/
    #access_token=73d0f8mkabpbmjp921asv2jaidwxn
    &scope=channel%3Amanage%3Apolls+channel%3Aread%3Apolls
    &state=c3ab8aa609ea11e793ae92361f002671
    &token_type=bearer

Will experiment with the one that lasts 4 hours and see what happens after been connected 4 hours to a channel, if it still can send messages or a “re-authorization” needs to happen causing the bot to disconnect from chat missing commands during that process.
