@A_A install worked for me https://smag0.solid.community/public/plume/ 
But l’ve @happybeing, I’ve got an issue creating my first post :
I can type a word, then I want to type a space, and this appear and disappear, like if there was a .trim() function that cut the last space, and every time I type a space, the first word is concatenated to himself.
I type another space and the word is concatenated another time, until 6 times . See below
