I'm trying to recreate the workflow of OpenMathLib/OpenBLAS#4751 (comment) , only with a gh-pages branch instead of a separate publisher repository.
The key point is for a workflow to push benchmark results to a branch --- and this needs a personal access token.
@martin-frbg could you please create and add a PAT? In my fork, the following permissions worked: actions r/w; commit statuses r/w; contents r/w; workflows r/w
