How to get .bchan file from Houdini for use in TouchDesigner?

I am trying to adapt a TD file from someone else, who has used a file in CHOP to import channel data from Houdini - I know it’s from Houdini because it is a .bchan file, which according to the TD documentation, is a Houdini channel export. However, I can’t figure out how to export this data from Houdini. For context, this is a rigged / moving FBX which I guess I need translated into .bchan. Any advice much appreciated!
