Using SNAP with non-Sentinel data

Hello, is it possible to use SNAP with data coming from other missions, in netCDF format (for example for visualising bands)? I am trying to open MSG data in netCDF format and, inside Bands, I can only see auxiliary data (attitude and orbit parameters) but I cannot see the bands corresponding to the instrument channels.
Thank you very much for your help.

In general SNAP support a broad variety of missions.
MSG is not explicitly supported and I don’t know the data. It can be that the data is not well read.
Is the data multi-dimensional? This can be one of the reasons why it is not shown correctly.
