In this work, we present a census of Ly$\\alpha$ escape fraction ($f_{esc, Ly\\alpha}$) of 165 star-forming galaxies at $z=4.9-6.3$ using their H$\\alpha$ emission directly measured from FRESCO NIRCam/WFSS data. We search for Ly$\\alpha$ emission of each H$\\alpha$-emitting galaxy in VLT/MUSE data. The overall $f_{esc, Ly\\alpha}$ measured by stacking is $f_{esc, Ly\\alpha}$ is $0.090\\pm0.006$.
