Slack Updates:

• Added test attendance button in menu bar that sends dummy message to channel
• Manual attendance button for testing and manually sending attendance message
• Attendance and Leave Notification UIs are built natively in Slack’s Block UI
• Slack Settings UI with more fields and description
• All Slack related operations happen in queues to be async and non-blocking
• frappe.log_error exceptions have str(e) in their body, not in title
• standardized date format using: Mar 10, 2024 (Tue)
• list of active users not available on slack to be shown

ToDo:

• Intercept slack api errors, show custom message instead of error code
• In whitelisted apis, return error http code if user input is invalid
• If possible, streamline error log (encapsulate saving errors and showing custom messages to user via a function)
• Approve and Reject action buttons functionality
• Half day in attendance notification not working properly
