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: http://docs.electrum.org/en/latest/tor.html 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 https://electrum.org/#download if you want to see the codes.

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

$ gpg --keyserver pool.sks-keyservers.net --recv-keys 2BD5824B7F9470E6

I checked the corresponding box: 1) Use a proxy for port 9050, 2) A proxy SOCKET5 127.0.0.1 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?
