@chetanchoudhary-sumo, I see a few issues:

• You should change the name of the file to match the file ID (for example, opentelemetry-collector-insights). It makes it easier to track the file.
• You need to create an entry in the sidebars.ts file for the new article so that it appears in the left navigation menu.
• The dashboard screenshots are broken. You need to set up permissions so that they appear in article.
• I question the location of the new article under https://help.sumologic.com/docs/integrations/hosts-operating-systems/opentelemetry/. @amee-sumo, can you tell @chetanchoudhary-sumo where you think the new article should go?
