[GNC] Finance::Quote terminal commands not working with Flatpack v:5.3 install

[doug brown]

I installed via flatpack Gnucash v. 5.3 on Linux Mint v. 20 OS and the terminal commands that I previously used to find sources for quotes on longer work.  Here is the output:
doug at sager:~$ gnucash-cli --quotes dump yahoo_json QCBMPXgnucash-cli: command not found
doug at sager:~$ gnc-fq-dump -v yahoo_json QCBMPXCommand 'gnc-fq-dump' not found, but can be installed with:sudo apt install gnucash
Any thoughts?
