Hi Layan,
We recommend using the "enablePersistence" option, which saves
the current state of the board, including the status of your tasks. To enable
this feature, you can set the "enablePersistence" option to
"true" in your code.
We also have a sample available on StackBlitz that demonstrates how to
use this feature in React:
https://stackblitz.com/edit/react-inq1md?file=index.js
You can find more information about this option in our documentation at
the following link:

API Link : https://ej2.syncfusion.com/react/documentation/api/kanban/#enablepersistence
Please let us know if you have any further questions or concerns.
Regards,
Vinothkumar
