Grafana image renderer on centos dos not start embedded chrome browser

Hi
I tried to install the grafana image renderer 2.0.0 on centos 7 from the plugin-linux-x64-glibc.zip.
When I try to use the plugin (with icinga2), I get:
lvl=eror msg=“Rendering failed.” logger=context userId=1 orgId=1 uname=admin error=“Rendering failed: Error: Failed to launch chrome! spawn /var/lib/grafana/plugins/grafana-image-renderer/chrome-linux/chrome EACCES\n\n\nTROUBLESHOOTING: https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md\n

Using the separately installed chromium works.

Any ideas how to fix this?

Regards
Matthias
