[ubuntu] 19.10, chromium snap and keepassxc

I have successfully upgraded from 19.04 to 19.10.
As part of the upgrade, it appears that chromium is now a snap package.
I use keepassXC and KeepassXC-Browser which has worked very well for me until today.
After the upgrade, I get the following:

The KeepassXC helper script tells me that browsers installed as snaps are not supported at this time.

Is there some way round this?
How can I install a non-snap version of chromium?

Thanks in advance
