How to use SCIM for keycloak with atlassin access

I would like to configure keycloak with Atlassian access via user provisioning(SCIM).
I dont seem to have an idea in how to use this GitHub - Captain-P-Goldfish/scim-for-keycloak: a third party module that extends keycloak by SCIM functionality but an advice and help is highly welcome. Thanks
