How can I add a scrollable multiline edit text in a nested scroll view in xml?

I am trying to create a posting fragment. It basically has a LinearLayout containing a TextInputLayout for text input, posting buttons, etc., and a RecyclerView to display posts. At the top of the page, users can write text in a multi-line EditText with a maximum of six lines. The issue is that when I type in the EditText, I can't scroll within it, but I can scroll the entire page. I want to be able to scroll both the RecyclerView and the EditText separately. How can I achieve this?
