Just use the python interpreter in the venv in the hashbang line.

For example, here's the first line of one my scripts:

#!/usr/local/share/wds/venv/bin/python3

As you can probably guess, the venv is in /usr/local/share/wds/venv.

There is no need for wrapper scripts which activate the venv. Python
does that all by itself.

I have a small script, install-python[1], to assist with setting the
hashbang, but if it's just a few scripts you can simply edit it manually.
