Field Calc: ST_MakeEnvelope in the Geometry Group

[pigreco]

Feature description

it would be useful to have in QGIS core the same function as PostGIS (ST_MakeEnvelope), in order to quickly create a bounding box using the coordinates copied from the status bar, in particular in the extension function:

make_envelope(756594,4068816,777241,4081345, replace(@project_crs ,'EPSG:',''))

a thousand thanks

Additional context

Currently to create a bbox I use the following expression:

 bounds(
 make_line(  
 make_point (756594, 4068816),
 make_point (777241, 4081345))
 )

the new function would avoid calling other functions like make_point and make_line

make_square is close enough, imo.

make_square is close enough, imo.

The make_square always draws a square and so here's what happens:
