What is really needed is the ability to edit the STL model.
As above, the STL file is a (generally triangular) mesh format.
The two most well-known mesh-editing programs are Meshmixer and Blender.
If you put ‘meshmixer alternative’ into a search, it will suggest other options.
A lot of what will work best for you depends on the shape of the object. If it is an ‘engineering’-type object, converting to STEP and working on the 3D solid might be a good move. If it is a more ‘organic’ or ‘sculptural’ object, keeping it as STL is probably the way forward.
