I94 Extension information

Hi,
I am in L1-B, and I am completing my Max 5 years by this October.
My i94 is expiring by 10th Sep 2022, but my max out is 16th Oct 2022.
Currently my VISA for European countries is in process and the passport sent to embassy for the VISA approval.
What is the best way to extend my i94 till my max out dates? Please provide your thoughts.
