[Copilot]

• Explore the repository structure and understand the documentation
• Locate the sentence that needs to be changed in certificates.mdx (line 387)
• Verify there are no other similar occurrences that need updating

• Build the documentation to ensure no syntax errors
• Review the final changes to ensure they're minimal and correct
• Complete the task

Original prompt

Change a single sentence in the "Update certificates using Temporal Cloud UI" section of docs/production-deployment/cloud/get-started/certificates.mdx.

File to edit:

• docs/production-deployment/cloud/get-started/certificates.mdx (commit b137f5c)

Current content (around the step to delete the old certificate):

"9. Return to the Edit page of the Namespace and select the CA Certificates card."

Requested change:

• Replace that sentence with: "9. Return to the Edit page of the Namespace and select the Authentication card."

Rationale:

• The Authentication card is the correct place in the Temporal Cloud UI to manage CA certificates; updating this instruction prevents confusion and aligns steps 4 and 9 which both reference the Authentication card.

Requirements for the PR:

• Update the sentence in the specified file exactly as shown above.
• Preserve surrounding formatting and numbering in the markdown file.
• Include a concise commit message such as: "docs: refer to Authentication card instead of CA Certificates card in certificates UI instructions"
• Open a pull request on temporalio/documentation with the change and a short description summarizing the fix.

Please create a branch, apply the change, and open the pull request. If there are any other occurrences of the same incorrect sentence in the repository, please update them as well and include those edits in the same PR. If you cannot find additional occurrences, create the PR with the single-file modification.
