PT Isochrone access_profile & egress_profile

Hello, I’ve been working on isochrones using Graphhopper, which so far has been a great experience. For now, I’ve gotten the request to include biking as access and egress methods in public transport. While this seems supported in normal routing engine, when adding the parameter in the isochrone-pt endpoint, no change is apparent.

Maybe I’m underestimating, but I imagine since it’s already included in routing engine, it might be feasible to also include it in the isochrone endpoint. Or maybe it’s already there, and I’m having some other issues.

Can anyone help me with this?
