I have never tried on a phone!it’s not the finding them that is irritating, but the endless scrolling to get nowhere. Not the group’s fault just facebook clunky technology. So faster searching the specific/basic sites - service public, impots gouv, ursaff etc etc which are generally pretty clear.
(Mind you, since OP has not replied since early in the thread he may well be among the unbelievers who don’t listen to advice that isn’t what they want to hear. It’s all doable, you just have ro do it correctly).
