 The authors report a tentative detection of this isotopolog in the ReExploring Molecular Complexity with ALMA survey at 3 mm. Only one unblended and one partially blended line were identified, many more were severely bleded or too weak. The derived CH<sub>3</sub><sup>18</sup>OH to CH<sub>3</sub><sup>17</sup>OH ratio of ~3.3 is along <sup>18</sup>O to <sup>17</sup>O ratios found for other molecules in the Galactic Center as is the CH<sub>3</sub><sup>16</sup>OH to CH<sub>3</sub><sup>18</sup>OH ratio of 240.\\ The authors report a tentative detection of this isotopolog in the ReExploring Molecular Complexity with ALMA survey at 3 mm.

 +The authors analyzed archival ALMA data near 231.89 GHz and 236.5 GHz and derived a CH<sub>3</sub><sup>18</sup>OH to CH<sub>3</sub><sup>17</sup>OH ratio of ~3.4–3.5, which corresponds to the expected <sup>18</sup>O/<sup>17</sup>O ratio at this galactocentric distance, reiteration the potential of methanol as a proble into the <sup>18</sup>O/<sup>17</sup>O ratio, as already done by Müller et al. in the previous paragraph.\\
