Here is the photo of the Otten charger (Otten sent me this photo because I wanted to be sure it was the right plugs).
Just say them it is for an FXS

I've bought it at  https://www.otten.de/e-mobilitaet/elektromobilitaet.html
Just send them an e-mail.
No change to make after buying it, just plug and play

The Otten charger I have bought has a type 1 plug, a shuco. I have added a cable because the Otten cable was too short for me, and changed the shucos for  french type 1 plugs. I could use a shuco/type 2 converter, but I don't really need it, so I use only the type 1 at home and with the public chargers. GT13013 (who friendly advised me for this charger) use this converter. I charge at 3.3 kW, and I can add the internal charger too to obtain nearly 4 kW. It charges then around 1% per minut.
No canbus, it is the simple charger.

I did two walks in the Alps this week, 110 km and 113 km, starting at an altitude of 400m and arriving at 1750m (Chamrousse) and 1370 (Alpe du Grand Serre). On arrival I had around 9% battery left. I'm so satisfied with my FXS, great motorcycle !

Should the charger stop charging automatically upon reaching 100% SOC / a specific maximum pack voltage or does it have to be unplugged before reaching a full charge?
For clarification, I am referring to the "dumb" version of the Otten Lader without can bus integration.

The answer is yes, it stops automatically. It's how it works for me.
