Framework with Tabulator library

When try to Download Table Data via respective handler triggers, it appends to the URL therefore routing to F7 404 page.
This new route URL:
Has any one worked with this library with Framework7? and how possibly can I prevent routing to 404 page.

// Buttons for exporting table data

When I init a new project with same code, it works fine, but with F7, routing issues.

You need to add “external” class to these links to prevent router from handling them

Thanks @nolimits4web
However, I’ve tried adding the external class to these buttons(they are not regular anchor tags) but buttons with type button to prevent any routing which does not seem to work as it still appends to current URL
URL before I click any of those export buttons http://localhost/gaf/#/

URL after I click any of those export buttons http://localhost/gaf/#/blob:http://localhost/1538000d-bafc-426f-b69f-82c71a5c2803 appended URL string indicated in bold.
