**Problem description**
Certain games failing to fully launch (Elder Scrolls Online and Origin/Mass Effect:Andromeda)
This seems to be related to Thawte SSL certs failing auditing and being removed from Distros as trusted certs:

https://www.reddit.com/r/debian/comments/hwdht8/how_to_add_3_missing_certificate_to_debian/
https://www.thawte.com/roots/

Because this actually is at the Host level and flatpak has its own filesystem layers it seems like this might be fixable in the flatpak in an easier fashion.
I found as a test, that if I copied the certificates.crt from Manjaro and was able to launch (see attached)
[ca-certificates.crt.txt](https://github.com/flathub/com.valvesoftware.Steam/files/5992259/ca-certificates.crt.txt)
But ideally I wouldn't want the untrusted certs usable by the rest of the host system.

**Does this issue reproduce with native Steam**
Yes
