OpenSearch Dashboards session ttl with SAML

Is there a way to extend a session ttl for users?
Right now after about an hour user is logged out and redirected to SSO page and then to the home page which means all search results are lost.

I tried adding these to OpenSearch Dashboards config:

opensearch_security.cookie.ttl: 43200000
opensearch_security.session.ttl: 43200000
opensearch_security.session.keepalive: true

and also these to OpenSearch security plugin config:

        http_enabled: true
        transport_enabled: false
        order: 1
          type: saml
          challenge: true
              # 24 hours
              expiry: NOW+1440

but didn’t help.

What do you think?

Where you able to solve this?
