Disable Authentication in Elasticsearch App for Samba Spotlight test

Hello,

does someone know how to disable the basic authentication in the ElasticSearch App. This is for an Spotlight Index test with Samba and unfortunately it seams that there is no possibility to tell samba how to authenticate:
https://www.samba.org/samba/docs/current/man-html/smb.conf.5.html
https://lists.samba.org/archive/samba/2021-March/235118.html

Here is a way how it should work if you could edit the config of the app

      xpack.security.authc:
        anonymous:
          username: anonymous
          roles: superuser
          authz_exception: false

But I don’t know this cloud be entered in the GUI if it is possible at all…
