Need help with older DJI Osmo Raw lens firmware

Anyone have any experience with older Osmo products? I've got a DJI 15mm MFT f1.7 lens that needs a firmware update to 1.1 to get it working on Panasonic and Olympus cameras.

Apparently it can only be done through a DJI product (in my case I have an Osmo Raw Zennuse x5r) but I cannot find any concrete guides on how to do it.

Anyone done this in the past or know how to update the lens specifically?

Thanks
