can anyone help me with the Threema-Node?
I have Node-Red running in a Docker-Container on a Synology DS918.
I have installed the Threema-SDK, I have the public key, the private key, the secret of the API and I have my ID.
But I do not understand what to enter in "SDK Exec"
The Threema gateway is installed to opt/iobroker/threema-gateway-venv
So I tried opt/iobroker/threema-gateway-venv/bin/threema-gateway and several other... but nothing works.
msg.error from send-message node is
"Error: spawn opt/ioBroker/threema-gateway-venv/bin/threema-gateway ENOENT"
