How can I get two fermions one goldstone boson interaction in a SARAH model ?

Please, read the manual!

I am able to find all the vertices which include physical fields (e.g., SSS, SSSS, SSV, SSVV, SVV, FFS, FFV, VVV, VVVV, GGS,
GGV). But I also need the vertices including two fermions and one Goldstone boson. Can you help me out, please?

Goldstones are scalars.
