According to the Keikai JSP guide, It seems to be possible to hide ZK Knowledge from using Keikai JSP tag.
Further idea is that if we can use an embedded JS to include the JSP tag, it would be great.
<zssjsp:spreadsheet id="myzss" ...>
// init it
let uuid = kBootstrap.build('myzss', 'path');
// release it after something happen
Refer to ZK Embedded JS
