What is the best issue tracker for Slack in web studio?

Question

Task Management

We switched to Slack, saw its great flexibility and the ability to expand with other applications. We want to add a task tracker. Please advise who has already gone through this difficult choice and is already working in conjunction with a tracker with Slack.
Minimum requirements:
1) creation and distribution of tasks within the team
2) tracking the status of tasks
3) specifying deadlines
4) accounting for the time spent
Ideally:
5) The ability to access customer tasks - helpdesk (I would very much like)))
6) reminders
7) visualization in the form of a kanban board and a gantt chart
8) creation of subtasks
