how do I add a new colleague who is also allowed to process questionnaires

Multiple accounts under one supply chain file

You add a colleague through the team settings of the account, not by sharing your own login credentials. Each account remains linked to the same supply chain file, so the colleague works with the same source data: the same answer to in which countries the enterprise has establishments, the same figures at annual turnover, the same certificate at ISO 9001. So you don't have to retype or export anything — from the first time your new colleague logs in, they see the same status as you.

What a colleague gets to see, you set yourself. Someone who only handles the cybersecurity lists doesn't need to have access to the financial answers, and vice versa. You arrange this per subject or per source, not per question — there is no fine-grained permission structure per individual question. If you want a colleague to see an answer but not be able to modify it, you set them to a view role; if you want someone to be able to confirm and submit to your customer's portal themselves, you give them the edit role. The confidentiality button works independently of who logs in: an answer that you have marked as confidential remains that way for every colleague you add, until someone with the right role resets it.

What this is based on: the supply chain file, not your customer's portal

This works this way because the platform itself is not a third party's portal: we don't log in anywhere and nobody at us reads a completed list. So team access is entirely in our own system, separate from how your customer's customer secures their own portal. Pay attention to one thing that few entrepreneurs expect: data that you enter at the statutory name or the registration number comes directly from the Business Register, and those basic data are the same for everyone with access to the file — a colleague can view them but cannot secretly modify them, because the source is the register itself, not a separate input field.
