I followed our documentation guide and I could install the plugin properly. After performing all the steps of the guide, I used the following search options to find the plugin
As you can see, the plugin is there and after installing it, new items in the top bar appeared. Does the plugin appears for you now?
In case you can't see it, could you please share with us the output of the following command?
ls -la /opt/bitnami/apps/odoo/lib/odoo-*/odoo/addons/bi_professional_reports_templates/
