As the modules have been updated it is ready to be installed. Furthermore, you can go to the apps module and search the respective module that you have updated. In addition, avoid the “apps' ' filter from the search bar for your new application to be visible.
An aspect to be noted regarding model updates is that some custom modules may crash the database or make some conflicts and depict errors. Therefore, it is better before installing the new module that you just keep a backup file.
Furthermore, after the backup of the database is done, search your custom module name and install it by following the procedures mentioned above. In addition, subject them to sophisticated testing before fully functioning with it. Moreover, it is important to consider translations when we perform customizations in Odoo.
