Hybrid SIEM approach

We have a principal SIEM running on prem. We have a person that almost exclusively sees after it and initially responds to alarms coming from the SIEM.

We also use Azure in the company and have Sentinel. However, we use Sentinel very little.

Can you give me some examples or ideas of using both SIEMs? What are good scenarios where utilizing both can help with incident detection and response?
