In QGIS, how could I get the attribute of the nearest line to a polygon with an expression (or virtual layer)?

I wish to create a new field in the polygon layer(in this case the parcels) with the names of the streets (the line layer) that are nearest of them. I thought I could use aggregate but I didn't find any nearest function to go with it.

The following expression should work :

array_to_string(overlay_nearest('Streets', StreetNameField))

Adapt the expression to your data structure.

From QGIS 3.16 on, i think.
