Group Rows in Excel Online (oos_2016)

Hello. I found a similar discussion in 2016, but the same question is of interest at the moment. We have the Office Online Server 2016 latest version installed, integrated with Nextcloud. The issue is with using Excel files. Is there any way to activate the row and column grouping function? If I open a document where grouping is already present, the file opens without any problems and the grouping is displayed. However, it is not possible to create grouping in Excel Online.
