DJI Mic Mini on "older" iPhones (13/14/14 Pro)

I have recently bought a brand new DJI Mic Mini, which I predominantly use with my mirrorless camera, but I would also like to use it with my iPhone sometimes. Problem is that my phone (iPhone 13 Pro) is still using obsolete Lightning port, also the genuine DJI Lightning adapter doesn't come in the box, and in my country is either very hard to find one or is being sold separately for much higher price than the official one, which wouldn't suit my needs because I would use phone for a very specific shoots.

Is there any way to use DJI Mic Mini with older iPhones other than the awful Bluetooth connectivity? Tried to connect the receiver on my phone via basic Type-C to Lightning adapter (supports both power and data) and the mic doesn't connect at all. Are there other 3rd party adapters/cables that can work with the mic itself?
