For the Spark can this cable be used? https://www.amazon.com/dp/B07214 ... dp_T2_OC7GzbX5BQGMQ
Looking for an OTG Cable to Lightning.  I have an OTG adapter to USB and it fits but it's a little wobblely.

Yes, Mavic cables work.

This is the one I got, works well. I use it with a short 8" lighting cable to avoid a bunch of loose wires
