Modifying documents is not permitted in MongoDB Compass Readonly Edition.

You can edit existing documents in your collection. When you edit a document, Compass performs a findAndModify operation to update the document.

You can also add a new field at the end of the document by pressing the tab key when your text cursor is in the value of the last document field.

You can modify documents by clicking on existing field names or values and making changes. In this example, the flight status was changed from L to M. Changed fields appear highlighted in yellow:
