curl -XGET -I -sH 'Accept-encoding: br' -H 'Cookie: security_authentication=xxx' https://playground.opensearch.org/1/bundles/plugin/observabilityDashboards/observabilityDashboards.plugin.js

What do you want to do?
Tell us about your request. Provide a summary of the request and all versions that are affected.
Dashboards sends minimized javascript for each plugin on page load. Some user choose to add a proxy in front of it for custom auth and security purposes. The largest javascript file is from observability plugin around 12MB, which exceeds some proxy or gateway maximum response size limit. Dashboards supports brotli and gzip (observability would be around 2.5MB) in addition to plaintext, but this is not documented and user might not know how to get dashboards to send compressed data instead of plaintext.
What other resources are available? Provide links to related issues, POCs, steps for testing, etc.
compression is added in webpack and available in OSD installation https://github.com/opensearch-project/OpenSearch-Dashboards/blob/7a8c281facb921d4af8aeeaa1ef80adb7d85b2ba/packages/osd-optimizer/src/worker/webpack.config.ts#L291-L302. might need OSD members to provide more technical details
