Ensure users know how to obtain lookup group credentials
Description
In order to use lookup via the ibis client, developers need to have group credentials. Provide documentation on how these are obtained (and link to information on storing these credentials).
It's possible/probably a process does not yet exist. @ek599 was direct to contact @rjg21 to get credentials which is not a scalable process.
Documentation is owned by comms and liaison with them is needed.
Acceptance criteria
- documentation clearly provides developers with information needed to get credentials
