Auto Authentication in Embedded link (AWS Opensearch)

I have hosted AWS OpenSearch(ELK) and with that Kibana also get hosted. So I have created a dashboard in Kibana where I get the embedded link and insert it to my HTML code. It ask me to login Everytime. If I host a EC2 instance and install Nginx in it and is it possible if I configure Nginx.conf and provided the access credentials to it so whenever my website gets loaded Visualization inserted in my website through Kibana Embedded Link it should not ask for authentication.
