Theming contact form

Hi every one, i spent the day fighting and don't get the solution :(
I would like in my form--contact-us.html.twig get all my fields and their labels but separately, for now i have something like :

{{ element.group_info.field_issuer_civility }}
{{ element.group_info.field_issuer_last_name}}
{{ element.group_info.field_issuer_first_name}}
{{ element.group_info.field_email_contact}}

{{ element.form_id }}
{{ element.form_build_id }}
{{ element.form_token }}
{{ element.actions.submit }}

the problem is each field print a container then a form_element wrappel then the label and field, is there a way i acces directly and print only the label and field ? si i can place it exactly where i want in my html ?

Thanks in advance.
