Fairphone 5 What spare part is the microphone 1 (bottom) located

Hello Fairphone Forum,

My Fairphone 5’s bottom microphone (Mic 1) no longer works. Could someone tell me which spare part contains this microphone? Is it part of the speaker module, or is it integrated into the core module?

Unfortunately, the troubleshooting page can’t identify the correct part for me because my IMEI belongs to a refurbished device:

“The product you have selected does not match the IMEI/serial number you have entered. Please revert back to the troubleshooting section and choose the correct product. If you are unable to determine which product you have or you have installed a different operating system, reach out to our Customer Support Team.
Product IMEI belongs to: FP5 Refurbished”

Thank you in advance.
