Assist integration with teams

[ehsan]

I'm trying to install Atlassian Assist in teams and I'm getting below error:

Your trial is over :( Please go to https://teams.halp.com to start your subscription.

I've tried to go to: https://teams.halp.com/settings/queues. but I can't see "queues" and and I can't make any changes there!

I'm using jira service management cloud (free).

Thank You!
