| Summary:
The Fermi Bubbles (FB) are a pair of large-scale ellipsoidal structures
extending above and below the Galactic plane almost symmetrically aligned with
the Galactic Center. After more than 10 years since their discovery, their
nature and origin remain unclear. Unveiling the primary emission mechanisms,
whether hadronic or leptonic, is considered the main tool to shed light on the
topic. We explore the potential key role of MeV observations of the FB and we
provide a recipe to determine the sensitivity of Compton and Compton-pair
telescopes to the extended emission of the FB. We illustrate the capabilities
of the Imaging Compton Telescope COMPTEL, the newly selected NASA MeV mission
COSI (Compton Spectrometer and Imager), as well as the expectations for a
potential future Compton-pair telescope such as AMEGO-X (All-sky Medium Energy
Gamma-ray Observatory eXplorer).
