Can I export a 3D gameObject made in unity as an fbx file to edit in blender?

I made a 3D character in unity, made up of a bunch of capsules, cylinders and spheres, all children of an empty gameobject of the characters name (and feet children of respective legs, pupils children of respective eyes etc.). i did apply a material to colorize the different parts, i figure that might have a hard time translating into another program. ive come to find traditionally you would do this the other way around, as i was prototyping the character size in relation to the size of my scene and other gameobjects i also created in unity. i havent gone through the best practices docs or studied workflow at all, just doing me, so if im doing it wrong please let me know, just trying to figure this out day by day. thanks for reading

i can only figure out how to export the gameobject in question as a unity package.
