KeePassXC also has a cli interface suitably named keepassxc-cli, so for TOTP in the terminal its something like:

   keepassxc-cli show -q "$KEEPASS_DB_FILE" "$ENTRY_NAME" --totp
   <type password>
   <prints totp>

edit: doubly so specifically regarding Authy since theyre discontinuing it on the desktop in a few months.

The keepassxc CLI reopens the database separately; it's actually possible to use git-credential-keepassxc† to do the scripting instead because it acts more like a browser (so it interacts with the already running instance of KeepassXC).
