It is often useful in a Flow to capture a signature from a user. This component leverages the Signature Pad project located here: https://github.com/szimek/signature_pad
In your player code add the following references:
<script src="signature-pad.js"></script>
You will also need to include the references from the core signature pad project: https://github.com/szimek/signature_pad
If you do not have a location to upload these files, you can use your Assets located in the draw tool. Simply upload the files and grab the file location.
