ExtensionInstallForcelist doesn't work

We are trying to install two extensions (Windows 10 accounts and Prowise) for Chrome via Intune. But we can't find a way to install both of them at the same time.

Name: ExtensionInstallForcelist

OMA-URI:  ./Device/Vendor/MSFT/Policy/Config/Chrome~Policy~googlechrome~Extensions/ExtensionInstallForcelist

Valuetype: String

Value: 

<enabled/>
<data id="ExtensionInstallForcelistDesc" value="1&#xF000;ppnbnpeolgkicgegkbkbjmhlideopiji;https://clients2.google.com/service/update2/crx&#xF000;2&#xF000;jdnhaegemihbmjieadghflanppgkcmgk;https://clients2.google.com/service/update2/crx"/>

What are we doing wrong? We also tried to create two separate lines with /1 and /2 after the OMA-URI but this didn't work either.
