Then I deleted the icon from my home screen by mistake.
And now I do not know how to put it back.
I swear that I used to have "Save to Home Screen" or something similar in Chrome (this is how I got the shortcut in the first place), I now only have "Open Assistant" (shown by the arrow)
When choosing "Ouvrir Assistant" ("Open Assistant"), Home Assistant opens full screen like a PWA - it is how it opened from the home screen shortcut.
How to save that page to the home screen?
