Tooltip and ReadOnly property [RESOLVE]

Hello everyone!
I’m using the Gantt library for my project and no changes to the chart should be possible.
That’s why I added read_only property.

gantt.config.readonly = true;

But tooltips are no longer available and I wanted to modify them to add more specifications and information to tasks.
How can I do ?
Thank you in advance


I’ve changed the calling order of libraries.
