As a workaround, you can paste it in a file, copy the file in the template and run the file with something like:
bash "$MYFILE"
Where, $MYFILE is replaced by your real file path.

Tested on latest updated Waydroid vanilla (no GApps) version, and Waydroid qube set up as per your guide above.
…found the answer already …
