This was reported as an issue against node months ago and has not been addressed by the author, it appears that the node has been abandoned.
Are you sure your colleagues are able to see it? There is another odbc node, @ais_automation/node-red-contrib-odbc. Perhaps it is that node that they are seeing.
You can install it manually if you want to, by going into your .node-red directory and running npm install node-red-contrib-odbc
then restarting node-red and refreshing the browser window.
