Derive angles from Landsat-8 OLI atmospherically corrected data (LC8SR)

I would like to use the biophysical processor to derive LAI FVC and FAPAR from Landsat-8 data.

SNAP 8 I import Landsat-8 OLI atmospherically corrected (LC8SR) acquisition, but when I start the biophysics processor I get the following error

in fact, scrolling through the bands I cannot find the corners and therefore what is reported in the error message is correct.

I then ask how I can derive the angles from the Landsat-8 data required by the biophysical processor.
Thanks in advance for your reply
