Forgeops - AM - how to install Custom Authentication Nodes

Hello
We are doing a PoC, for a complete deployment of forgeops on AWS.
I am consulting you, because we have some requirements for the deployment.
1- Extend the identity DS schema.
2- Install Custom Authentication Nodes.

For point 1, we will do it by modifying the 99-ext.ldif {forgeops/docker/ds/idrepo/config/schema/99-ext.ldif at master · ForgeRock/forgeops · GitHub} file.
For point 2, we have NOT found it in the documentation.
Someone has done it and could tell us where to leave the jars, or if you have the link to the documentation.

Thanks.
Regards.

Have you already gone through this documentation?

Hi anishetty, thanks for your answer
Yes, we have an on-premise platform infrastructure with custom nodes and we want to move it to forgeops on AWS.
So we are analyzing to place it in the Dockerfile in the creation of the image.

But we want to validate if our approach is correct.
Thank you.
