To access the account object in Salesforce, users need to have permission to the account object on their profile or permission set. Permission to an object determines what users can do with records of that object, such as create, read, edit, delete, view all, or modify all. If users do not have permission to an object, they will not be able to see or access that object in Salesforce. References:

Recurring tasks are tasks that repeat at regular intervals, such as daily, weekly, monthly, etc. They can be created by users who have the permission to create recurring tasks, which can be enabled by administrators in the user profile settings. Flow, workflow rule, and recurring activities are not valid options for creating recurring tasks in Salesforce. References:

Omni- Channel can route work items to agents based on their predefined capacity and skills, ensuring that they are working on the right tasks at the right time. Knowledge Management, Escalation Rules, and Territory Management are not related to agent capacity and skill set. References: https://help.salesforce.com/s
