privacy – How to check if Electrum masks my IP with Tor proxy?

When I launch Electrum from the command line, I see this size:

(python3: 7069): dbind-WARNING **: 14: 09: 58.452: can not register with the accessibility bus: has not received a response. The possible causes are: the remote application did not send a response, the message bus security policy blocked the response, the response time has expired, or the network connection has been terminated.

What does it mean?

I just installed Electrum after this tutorial: I followed the instructions of this topic "Option 2: Multiple servers but Tor Main".

I've installed Electrum using the command line on Ubuntu, check the box "Installing from Python sources"on this link if you want to see the codes.

And I've used this code below to download the signing keys:

$ gpg --keyserver --recv-keys 2BD5824B7F9470E6

I checked the corresponding box: 1) Use a proxy for port 9050, 2) A proxy SOCKET5 9050.
And the circle icon on the bottom right is blue, it means it works, I guess. That's all I have done. A bit easy compared to Bitcoin Core

How can I check if the Electrum uses the "Tor IP" instead of mine? I am safe with this configuration?
