Hi @chris d101 thank you for posting in the community! Just to make sure that we are on the same page please review our Google Add-on article from the Lucid Help Center and let me know if you have any questions about the set up or intended functionality.
After you have installed the add-on for Google Docs you should be able to find it in the right hand side tool bar. This Community Post (in English) demonstrates the functionality of Google Add-ons and what it looks like.
If you are still not able to see the add-on in Google Docs could you please share the following information:
- A screenshot of the issue.
- A screenshot of the associated Javascript Console output after reproducing the issue. You can open your Javascript Console by pressing Ctrl + Shift + J (if your computer is a Windows / Linux) OR Cmd + Opt + J (if your computer is a Mac).
Please let me know if you have any further questions!
