Trying to add To Block under the To Do column

[xozxro]

I am trying to add a block to the 'To Do' column on my notion board in Notion Py. Currently, I have this.

page = self.client.get_block('https://www.notion.so/xyz') # this links to the default 'task list' page, as I can see when viewing 'page.title'
newchild = page.children.add_new(TodoBlock, title="Something to get done", status='To Do')

Can't figure out how to actually add the child block under the To Do list. What this yields is the block listing when I run

for child in page.children:
            print(child)

But not seen anywhere on my Notion in my browser.

Any help with this would be greatly appreciated, not finding much online in regards to this specifically.
