Trying to run the dishwasher in France. Nothing appears to be dishwasher liquid. This looks like the closest thing. Is that what it is?

You may have better luck looking for tablets.
Also and Lidl - if you have them in reach - do good ones.
Bonne chance!
@glennf it appears detergent adjacent. Like a water softener, surfactant for spot free drying. A bounce dryer sheet, oxy clean type of niche.
It also looks to be meant for machine dish washing. Not hand dish washing.
