Dark matter interactions with normal matter would happen if dark matter was WIMPs, Weakly Interacting Massive Particles. But cosmologists has recently more or less excluded natural - hot big bang thermally generated - WIMPs of the 10-1000 GeV range [ https://scitechdaily.com/dark-matter-destruction-ruled-out-as-origin-of-extra-radiation-in-milky-ways-galactic-center/ ].

With naturalness gone, the likelihood for dark matter interacting with anything else than the gravity it was discovered with becomes low. Then dark matter can have any mass between inflatons (about 10^-5 Planck mass) and normal matter (heaviest such at 100 GeV).
