ArcMap
One function is label features, which means that the specified field values in the layer can be displayed as labels in the main window.
After features, right-click the layer and you will find a gray feature name, convertlabelstoannotation. This function is provided in AE,
However, you cannot find the location where the field value is set. Create a note layer and generate a note based on the field values specified in the layer. Is a feature point conversion. It may be less efficient than the interfaces provided by AE.
I will not use that interface, so I can barely use it. In this regard, the most difficult thing is to create a new note layer. There are many attributes that need to be set, which is troublesome. below is the code Private void converttoannotationlayer (IMAP pmap, ilayer player, string fieldname, esrigeometrytype)
