DBeaver does not recognize declared variable when executing SQL script on SQL Server

We are using DBeaver Community Edition (v23.2.0.202309041200) as a client connecting to Microsoft SQL Server 2016 (v13.0.5101.9). The issue happens when executing the below SQL statements in DBeaver as a script.

declare @option as int = 2;

select @option;

The action "Execute SQL script", or by DBeaver hot key Alt+X, always fails on the selecting statement, with error message saying SQL Error [S0002]: Must declare the scalar variable "@option".. The error does not happen if we highlight the two SQL statements and go with action "Execute SQL query", or by DBeaver hot key Ctrl+Enter. The error does not happen either if we use Microsoft SQL Server Management Studio, so we do not believe the issue is related to SQL Server. **Our Question:** Is there any way we can use declared variables in DBeaver when executing a SQL script on MSSQL (Microsoft SQL Server)? We highly appreciate any hints and suggestions.
