The 5 min wait should be highlighted in the docs when creating APIs

Issue in /src/pages/guides/using/creating_rest_apis.md

Perhaps in a callout box or something.

Open /src/pages/guides/using/creating_rest_apis.md and read the API creation steps around the waiting period. Confirm how nearby callouts are formatted, then make the five-minute wait prominent in the relevant section. Done means the timing is easy to notice and the documentation remains consistent with the surrounding guide.
