It is possible to access teams on both the xBox One and a PlayStation 4/5.
This video also goes through the basics https://youtu.be/mfrSCeedsmE
This may not give access to all the features of teams (eg no camera), but it should allow for viewing of a lesson if needed. A logon for Xbox one is needed, not the school account. Once you have access to the edge browser, navigate to the office portal, I suggest using the LCETB.ie website for this. Once at the office portal page, the students office account details are needed to access office.
