external pro visitors

External professional visitors. Two options :

CMS public visit:
This is by far the easiest solution if you are (or have) a CMS guide. Follow this procedure if you don’t mind staying on the visitor path.
CMS professional visit:
Use this if you don’t want to stay on the visitor path or if you can’t find a suitable time slot with the public visits service.
