Hot super-Earths around M dwarfs show lower core mass fractions than predicted by their stars' refractory abundances, indicating roughly 1% water by mass sequestered in their interiors.
Note that GJ 1132 b was restricted to have an eccentricity of 0 thanks to its short period; GJ 1132 c’s eccentricity was allowed to float

Super-Earth masses and stellar abundances from NIRPS reveal tentative evidence for water-rich formation around M dwarfs
