PICO CMS limit to groups? + bug

hi, how could pico CMS be limited to certain groups, as the option is not available in the App list? thanks

i’ve removed and reinstalled pico, and now the group limitation is available …
nextcloud is always surprising …

ah … no … the option has vanished after trying to add a group and an error message …

pico is no more functioning, when clicking pico in settings
it leads to

funny!?
Logs refear to “picodeprecated”, is it the case? shall we not use this app?

pico displays in a new use account
but not in the previous user account that created a web site earlier
