At the moment, you don't have to do anything. The developer will have to update it prior to the release of macOS 10.16 (still unannounced) or it will no longer function after upgrading.
If they fail to do so, you can either find a replacement, live without it, or forgo upgrading to 10.16 until it is updated or can be replaced if it's something critical.
