Hello,
I have a problem with Zoopim integration on Magento 2.3.5.

The issues concern: pagespeed, violation of CSP and cookie 

As for CSP
I tried to create a module to try to whitelist the zopim widget (but it doesn't work well)

for the moment, I have disabled the restriction mode (otherwise it would not have loaded the widget)

I created a module in magento by whitelisting:

<?xml version="1.0"?>
<csp_whitelist xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Csp/etc/csp_whitelist.xsd">
<policies>
<policy id="script-src">
<values>
<value id="zopim1" type="host">*.zdassets.com</value>
<value id="zopim2" type="host">*.zopim.com</value>
<value id="data" type="host">'self' data:</value>
</values>
</policy>
<policy id="default-src">
<values>
<value id="zopim3" type="host">*.zdassets.com</value>
<value id="zopim4" type="host">*.zopim.com</value>
</values>
</policy>
<policy id="img-src">
<values>
<value id="zopim5" type="host">*.zopim.com</value>
<value id="zopim6" type="host">data:</value>
</values>
</policy>
<policy id="connect-src">
<values>
<value id="zopim7" type="host">*.zopim.com</value>
<value id="zopim8" type="host">*.zdassets.com</value>
</values>
</policy>
<policy id="font-src">
<values>
<value id="zopim9" type="host">data:</value>
<value id="zopim10" type="host">*.zopim.com</value>
</values>
</policy>

<policy id="frame-src">
<values>
<value id="zopim11" type="host">*.zdassets.com</value>
<value id="zopim12" type="host">*.zopim.com</value>
</values>
</policy>
</policies>
</csp_whitelist>

As for speed, as soon as I enable the module, the pagespeed score drops a lot.
currently magento is in developer mode and is still under development, however this widget penalizes a lot.

as for cookies, I would need that once you click on the "accept cookies"  button ( id="btn-cookie-allow" ) the widget loads.

Could anyone help me? I'm really in trouble and I wouldn't want to give up zopim.

thank you all in advance!
(I hope this post is also useful to other users who are struggling with magento integration.)
