If you have a requirement to allow auto approving of Time Entries, Expenses and Material Usage Logs in Project Operations, then you can achieve this by using a Power Automate Flow.
You need a trigger on creation of a Project Approval and then have a switch reading the ‘Entry Type’ which can either be:
- Time Entry – 0
- Expense – 1
- Material Usage Log – 192350000
Then for each of the three switch branches you will need to approve the related Time Entry, Expense or Material Usage Log

Approving the Time Entry
Entry Status = Approved

Approving the Expense
Expense Status = Approved

Approving the Material Usage Log
Material Usage Status = Approved
