Need a UI to provide task management

n8n will provide great workflow management for us, but we need a place where we can view the tasks, can anyone recommend a platform that would allow this?

Specifically within the tasks we create we want to be able to create a dynamic iframe. so that if a task needs a user interaction (including user specific token) via a URL with a callback, that way it would allow the task to be actioned within the task management platform (we did consider Jira but it could not meet the dynamic requirement).
