Whiteboard integration fails to start on CentOS7 because of libstdc++ version dependency

[Gummikavalier]

Description

When trying to use whiteboard, user gets the error: Impossible to load Spacedeck whiteboard "cURL error 7: Failed connect to localhost:9666; Connection refused (see https:\/\/curl.haxx.se\/libcurl\/c\/libcurl-errors.html) for http:\/\/localhost:9666\/api\/spaces"

In closer inspection Whiteboard/Spacedeck is not running at all on CentOS7 servers. Ubuntu 20.04 LTS installations don't suffer from this.

Integration fails to start on CentOS7 because of missing libstdc++ version dependency:

spacedeck.nexe.bin: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /var/www/html/nextcloud/apps/integration_whiteboard/data/spacedeck/spacedeck.nexe.bin)
spacedeck.nexe.bin: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /var/www/html/nextcloud/apps/integration_whiteboard/data/spacedeck/spacedeck.nexe.bin)
spacedeck.nexe.bin: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by /var/www/html/nextcloud/apps/integration_whiteboard/data/spacedeck/spacedeck.nexe.bin)

I haven't found a good way to fill out the dependency apart from compiling from source, which is not very maintainable scenario.

The last supported ones are: GLIBCXX_3.4.19 CXXABI_1.3.7

rpm -qa | grep -i stdc
libstdc++-devel-4.8.5-44.el7.x86_64
libstdc++-4.8.5-44.el7.x86_64

Would it be a plausible scenario that binary would be compiled as compatible with CentOS7 for https://apps.nextcloud.com?
