How do I stop "Simulation Data Inspector"?

I was analyzing some model a while ago and I enabled the Data Inspector, but now I'm not interested in that feature anymore. However, now, every time I run my model, Simulink shows a pop up window:

No data to record

Model 'myModel' has been configured to send logged workspace and MAT-file data to the Simulation Data Inspector. Based on the current model settings, there is no logged data in a format supported by the Simulation Data Inspector. Consider updating the model to stream signals to the Simulation Data Inspector.

How do I prevent this to happen? I don't want to record any data.

To resolve this error message in R2016b and ealier and stop recording any data, go to the Simulink Data Inspector (SDI) Icon in the Simulink Editor tab. If logging Workspace data is turned on, you should see a small record button over the SDI Icon. To disable logging, select the drop down arrow next to the SDI icon and click again on the "Send Logged Workspace Data to Data Inspector" to disable it.

Sorry, I can find "Send Logged Workspace Data to Data Inspector" in ver2015a, but can't find it in ver2019a. Where is it.

The option "Send Logged Workspace Data to Data Inspector" was removed from the SDI icon in R2017a, however it appears to be equivalent to the (still existing) model parameter "Record logged workspace data in Simulation Data Inspector":

That being said, disabling this option will only prevent SDI from loading workspace data (which is what caused the above error message for the asker), but there maybe still be many other reasons why SDI is active for your simulation. One obvious reason is logging signal data, another could be that you are logging Output or States data in 'Dataset' format as explained in this answer:
