I want to access the text file in pyz

python 3.x

I used the zipapp module to create a pyz archive file.
If pyz contains a text file, how do I access it?
In the case of Java, I think I can read the text in the jar file, but is Python impossible?

Example

test.pyz
|-- |-- main.py
`-- a.txt

• I want to access a.txt from within main.py
• If you put a.txt in the same directory as test.pyz, you can read it, but you want to put it in pyz
