permission failure on Linux / BSD installs

I'm using fyne on Debian 11 Bullseye.
when I follow the instructions at https://apps.fyne.io/apps/me.ankushjadhav.fynesweeper.html
I get the error:
failed to copy application binary file: open /usr/local/bin/

Does this mean I need to use sudo?
I would prefer to install it to ~/.local/bin instead. How can I do thar?

actually, I tried it wirh sudo, and that doesn't work either; it is unable to locate the command fyne - i see, it's insalled in ~/go/bin
