OnlyOffice spreadsheet context menus missing Insert Row / Column

Expected behaviour

When bringing up the context menu after selecting a row or column header in a spreadsheet, you should be able to get to an option to insert a row (when row selected) or insert a column (when a column selected). In the native OnlyOffice app for iOS, these are in the context menu:

• Row selected: Cut | Copy | Paste | Delete | Cell | >> Merge | Clear | Insert Top | Hide | Show |

• Column selected: Cut | Copy | Paste | Delete | Cell | >> Merge | Clear | Insert Left | Hide | Show |

Actual behaviour

The equivalent context menus in the Nextcloud iOS app are as follows:

• Row selected: Cut | Copy | Paste | Delete | Cell | More >> Show | Freeze Panes

• Column selected: Cut | Copy | Paste | Delete | Cell | More >> Show | Freeze Panes

Steps to reproduce

Select a row or column header in an OnlyOffice spreadsheet in the Nextcloud iOS app, and bring up the context menu

Reasoning or why should it be changed/implemented?

The Nextcloud iOS app does not seem to have any way to insert rows or columns into a spreadsheet. As a result, to make this kind of change from an iPhone, the user needs to jump out of the Nextcloud app and into the native OnlyOffice app, make the change, then jump back into the Nextcloud app for remaining work.

Start at the OnlyOffice spreadsheet context-menu entry point in the Nextcloud iOS app and compare row-header and column-header selections with the native OnlyOffice menus listed here. Done means both menus expose Insert Top and Insert Left and the behavior is verified on iOS; this issue names no source files or tests, so locate the relevant integration before choosing them.
