How to use the ve-sequence-utils.condensePairwiseAlignmentDifferences function in ve-sequence-utils

payloadToUse.pairwiseAlignments.forEach(([template, alignedSeq]) => {
        const condensedSeq = condensePairwiseAlignmentDifferences(
          template.alignmentData.sequence,
          alignedSeq.alignmentData.sequence
        );
        let re = /r+/gi;
        let match;
        const additionalSelectionLayers = [];
        while ((match = re.exec(condensedSeq)) != null) {
          additionalSelectionLayers.push({
            start: match.index,
            end: match.index + match[0].length - 1,
            ...highlightRangeProps
          });
        }
