// {
// 	"pubsubTopic": "...", // optional string
//  "startTime": 1234, // optional, unix epoch time in nanoseconds
//  "endTime": 1234, // optional, unix epoch time in nanoseconds
//  "contentFilters": [ // optional

// If the message length is greater than 0, this function should be executed again, setting  the `cursor` attribute with the cursor returned in the response
// peerID should contain the ID of a peer supporting the store protocol. Use NULL to automatically select a node
// If ms is greater than 0, the broadcast of the message must happen before the timeout
// (in milliseconds) is reached, or an error will be returned
