To decrypt the TLS traffic you need the (Pre)-Master-Secret.
For example using curl
on Bash (Linux) prompt:
SSLKEYLOGFILE=$PWD/mykey.log curl -L http://...
And add this file to wireshark.
For more information see: https://gitlab.com/wireshark/wireshark/-/wikis/TLS#using-the-pre-master-secret
The private key can only be used on old/outdated ciphers.
PS: better a long post than one with not enough info :-).
