contact for install XA certificates

[bpinsard]

Hi, the docs mention to contact to get the certs for install on XA.

yarra-framework.github.io/download/index.html

Lines 219 to 221 in 9a2bb93

	<h4>Certificates</h4>
	<p>To run the Yarra client on scanners with the XA-line software (e.g., MAGNETOM Vida or Sola), it is necessary to install software certificates before the client can be launched. Please contact us to obtain these certificates.</p>
	</div>

Is there a preferred email address to send such request?
Many thanks!
