How to make camera fit viewport in fullscreen mode?

Question

I'm trying to get my camera to fit the entire viewport (home button) in fullscreen mode
and this is what I've come up with so far:

import bpy

context = bpy.context.copy()
for area in bpy.context.window.screen.areas:
    if area.type == 'VIEW_3D':
        
        context['area'] = area
        bpy.ops.screen.screen_full_area(context, use_hide_panels=True)
        
        area.spaces[0].region_3d.view_perspective = 'CAMERA'
        bpy.ops.view3d.view_center_camera({'area': area})

but it keeps giving the error

RuntimeError: Operator bpy.ops.view3d.view_center_camera.poll() failed, context is incorrect

How do I fix this?

I guess I forgot the proper region, this should do the trick:

import bpy

context = bpy.context.copy()

for area in bpy.context.screen.areas:
    if area.type == 'VIEW_3D':
        
        #sets into camera view
        area.spaces[0].region_3d.view_perspective = 'CAMERA'
        
        #sets to fullscreen
        context['area'] = area
        bpy.ops.screen.screen_full_area(context, use_hide_panels=True)
        
        #sets camera to fit viewoprt
        bpy.ops.view3d.view_center_camera({
            'area': bpy.context.screen.areas[0],
            'region': bpy.context.screen.areas[0].regions[0],
        })
        break
