Inter-rater Reliability measure for ordinal data with multiple raters

I am wanting to obtain a measure of IRR for a diagnostics tool on the NHS. 6 professionals assessed an individual on multiple health domains such as

Behaviour
Cognition
Psychology
Communication
Mobility

Each professional gave a score between 1-6 for each domain when 1 = no needs and 6 = severe needs.

I am wanting to assess whether the 6 professionals are giving the same/similar mark to each domain as so to reveal the diagnostics tool as reliable.

Please suggest tests. Many thanks
