Who manages the workload and staff work planning?

Question

Work organization

Good day to all!
I would like to ask for advice and share the experience of more experienced colleagues.
The situation is as follows:
I work in a small web studio and I am faced with the fact that I need to know the workload of the development team in a form convenient for me, in order to be able to visually perceive the information and see where and who has some "windows" in time. In general, full-fledged planning of the team's work.
We work in Bitrix 24, the closest thing I need is Scrummbanfrom Siberiax. It has task cards, with a convenient view, and in principle, even supposed tasks that do not have complete information can be thrown there without assigning a responsible person until the complete information is clarified for setting the task. However, I did not find a solution in which, in the board format, for example, it was possible to look at the workload for all employees in the time section, perhaps something like a Gantt chart.
