This is the cable I use with my mini4.
I have used the OTG adapter as mentioned by
nilanjan118, but have found it can be cumbersome because it sticks out of the remote too much, and then a cable plugged into that.
I was afraid of breaking the pins in the remote if I continued to use it.
The cable I purchased has right angle connections and provides a clean tight fit without an excess of wire hanging around the remote.
