Hi There,

Thank you for your question. In order to handle this, you’ll need to have the SharePoint implementation on your side and then you can use our API to use these signatures.

To load the saved signatures you have on SharePoint, you can use the method importSignatures.

To save the signatures on your SharePoint drive, you can use the output of exportSignatures method.

In order to open your custom modal with the solution for SharePoint here is a code snippet to help you about how to open your modal instead of the local drive.

Webviewer({
 ...options
}, document.getElementById('viewer')).then(instance => {

  const { UI } = instance;

  const iframeDoc = UI.iframeWindow.document;

  // Setting up your modal to open the SharePoint drive files
  var modal = {
    dataElement: 'meanwhileInFinlandModal',
    render: function renderCustomModal(){
      var div = document.createElement("div");
      div.style.color = 'white';
      div.style.backgroundColor = '#132454';
      div.style.padding = '20px 40px';
      div.style.borderRadius = '5px';
      div.style.width = '100%';
      div.style.height = '100%';
      div.innerText = 'Modal to handle with SharePoint drive';
      return div
    }
  }

  // Listening to visibility changes into signature modal
  UI.addEventListener('visibilityChanged', e => {
    const { element, isVisible } = e.detail;
    if(element === 'signatureModal' && isVisible) {
      const pickImageButton = iframeDoc.querySelector('.image-signature-upload #upload');
      
      // Opening your custom modal when the user clicks to choose a signature in the local drive
      pickImageButton.addEventListener('click', (e) => {
        e.preventDefault();
        UI.setCustomModal(modal);
        UI.openElements([modal.dataElement]);
      })
    }
  });
})

I hope this helps, let me know if you have any questions.

Thank you,

Dandara
