Fail to install package on debian 11

Hi, I'm trying to install Otto Blockly on Debian 11. But I found that the packages has a dependence of libappindicator1 package. Which has been deprecated. Acording with this debian info: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=895037 has been replaced by libayatana-appindicator.
