Indoor Swarm by using swarm function in mission planner

hello everyone,

i am trying to link two(2) drones together for an indoor mission. in which gps is not available and positional data will be given by ethier RS t265 (non ros method) or hereflow. after reading again the documenation for arducopter i found the post about the swarm function within mission planner in where it specify sending GPS location from leader to follower, that being said will this function work if i uses RS t265 ( local NED) or using here flow (velocity)

thanks in advance!
