Libreoffice error: libicui18n.so.63: cannot open shared object file

Got this error after installing libreoffice 7.2.3 in Ubuntu 20.04 using apt:

/usr/lib/libreoffice/program/soffice.bin: error while loading shared libraries: libicui18n.so.63: cannot open shared object file: No such file or directory.

Here's the output of apt-cache policy libreoffice:

The solution (inspired from here) is to insert the following two lines under the comment lines in "/usr/lib/libreoffice/program/soffice" and in "/usr/lib/libreoffice/program/unopkg" to get both libreoffice and Mendeley working.

LD_LIBRARY_PATH="/usr/lib/libreoffice/program:/usr/lib/x86_64-linux-gnu/:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH
