If you read back through this thread you should find ways to do this that are more automated.
Fundamentally, you can use a URL call to create a Markdown note in an Obsidian vault using the draft content as the content of the file, or write that content directly to a Markdown file in the file system area the vault utilises.
So basically tap and done on an action, or assign the associated action to a keyboard shortcut.
If you want a summarised view, maybe have a read of this.
