Feature - review all fields optional/mandatory status

i’ll be reviewing all fields, many are mandatory and should not be that way. This will improve the customisation of forms, make helper texts better too

doc is private:

some fields are optional but are not possible to be hidden on the customisation menu … sometimes we see twice the hide toggle

when the helper text, dont leave it empty: “No helper text has been defined, click here if you want to create one”
