PHP Google Sheet API V4 - 在添加新行时更新已保存过滤器的范围

Currently the range of saved filter is not increasing when a new row is appended to the sheet.

Example: Filter - A1:BN2700 when the last row is 2700.

It is still A1:BN2700 when a new row appended and last row is 2701.

How can i fix this using PHP?

Thanks in Advance.
