How to edit text in parameters section?

[baldee]

I have a .png file from an AI generated image. The metadata stored from the generation is in the "parameters" section which I can view on the bottom of the window in the properties tab and the ExifTool tab...when I goto edit the Metadata tab → choose EXIF/XMP/IPTC and look for standard fields (ImageDescription, Comment, Title)...all the boxes are blank...for the love of Pete...how do I edit the metadata text in the parameters section? Thanks in advance

...Yes, I want to edit the text in parameters section...ExifTools is added.

The parameters tag is, as far as I know, exclusive to PNG files. You can use Exiftool to read and write string data in that tag from the command line, but obviously that's not inside XnViewMP.
