Gaia typically lists G-band apparent magnitude, as well as BP and RP colours. Using these, one can verify the position of the Be star on the HR diagram.
Typically, the listed magnitudes need to be corrected for reddening. The amount of reddening can be approximated through an absorption coefficient Av (Ag - Gaia band), that can be estimated from the fitted Nh obtained through X-ray spectral fitting (or the nh query on HEASARC). See here for example.
