As attached, only 5 icons are displayed at the top of the text component editing screen.
If you display it in full screen, more icons will appear.
With the current specifications, you cannot tell if there are multiple icons unless you use the full screen. Very difficult to understand. Request that all types of icons be displayed even if it is not full screen.
This has been reported to the engineering under the internal reference SITES-29243. The product team will triage this request to verify feasibility based on the prioritization model. This post will be updated according to Jira's status.
