Plug and Play USB Remote w Pi3B

I have a Rasberry Pi3B, paired with the official 7" Touchscreen and a HiFiBerry DAC+. I am hoping to avoid needing to mod it but wanting to get this to work with some sort of remote.

I do have the Remote Plug-In installed and I do see a few remotes listed. My question is this: What USB dongle do I need to get to work with these?

I know a few of the options (such as the JustBoom) are not around or easy to find anymore.

Any help appreciated.
