Get_transform_vector - get transform in wgs84 (4326)

Hello,
I´m using the get_transform_vector in order to get the transform of my bbox.
The result recived in UTM. Is there any convenient way to get the results in WGS84?

# Convert bounding box to UTM coordinates
bb_utm = geo_utils.to_utm_bbox(bbox)
transf = bb_utm.get_transform_vector(resx=10, resy=10)
