We can export the Datastream charts to Excel, Word or PowerPoint (only when the chart has been saved!). This is done by using the dedicated buttons:

A new window opens in which we can change the sizes, dimensions etc. When satisfied with settings, we click on Export Chart and the chart will appear in the MS Office program that we specified (Excel, Word, PowerPoint).

Exported charts in MS Office programs can be later updated using the Refresh Selection option within Refinitiv tab. We need to be signed in RWS on computer to use this function, so doing this is not viable on home computers.
