Explanation
A Service Appointment can be shared by clicking Sharing on the record if manual sharing is enabled in Field Service settings[51]. Auto-generated scheduled Service Appointments will be shared with resources if automatic sharing is enabled in Field Service settings[52]. The Service Appointment's parent record can be shared with the assigned resource, but this would not affect the sharing of the Service Appointment itself.
Making the dispatcher the assigned resource on the Service Appointments would not make sense if they are not performing field service tasks. References:

Explanation
Work types can be used to assign associated articles to work orders, which can be accessed offline by technicians using the Field Service Mobile App. The Salesforce Mobile App does not have deep linking to the Field Service Mobile App. Creating a custom Mobile App that syncs articles based on service appointment assignments is not necessary and would require additional development and maintenance. Writing a workflow that associates articles to work orders based on a picklist on the work order is not recommended and would not ensure offline access.
