Detailed Architecture of the L 98-59 System and Confirmation of a Fifth Planet in the Habitable Zone

The L 98-59 system, identified by TESS in 2019, features three transiting exoplanets in compact orbits of 2.253, 3.691, and 7.451 days around an M3V star, with an outer 12.83 day nontransiting planet confirmed in 2021 using ESPRESSO.
