Any way to notify Lyft about driver who went above and beyond?

I left my phone in a Lyft last night. I contacted Lyft through the website on my computer. The driver emailed me same night and drove the phone back to my place. I gave him $100 cash (round trip from my place back to the city would have been around $80).

The initial Lyft ride was $8, and I also tipped him $10.

I know drivers are independent contractors, but I'd like to reach out to Lyft if it would do anything for the driver. Please let me know if there is anything. Thank you!
