Join records with Line geometry

Hi All,

I am working on data with Line Geometry and would require some help to solve the below scenario,

While plotting them on map, I see there is small gap between lines in some scenarios and would like to join them together if the distance between two lines is less.

(Reason for this gap - There is an asset in between the lines which has Point geometry.- Not sure if this statement will help, JFYI)

Below is an example of different line geometries joining with each other, and there are small gap in some scenarios

I would like to join

1.  gap between Line 3 and Line 4.

2. gap between Line 5 and Line 6

I am not interested in joining parallel line, as they are far from each other

Any help regarding the above would be much appreciated.

Thanks
