A Revoice plug-in is applied directly to a region or regions in Logic, rather than via a channel-strip insert, enabling the audio to be captured quickly. That's the only aspect of it we use in this case. To get the processed audio back in to Logic just use the drag and drop method. Normally, with Selection-Based Processing, the plug-in processing is applied to a copy of the region concerned, so that the original is still available, but in the steps below we show how you can capture the audio without creating a copy of the region. See https://support.apple.com/en-gb/HT207467 for further details of how it works.
Bar Beat Position
If you are using the Bar Position plays at SMPTE setting in Logic you need to set the same offset value in Revoice Pros settings panel before exporting any audio from Logic.
