Question Importing Textmesh Pro package via command line

Hello, I want to use command line to automate the building process of unity projects. The unity project will be clean, like freshly pulled from repository, only has following 3 folders: Assets, Packages(with only 1 file in it: manifest.json), and ProjectSettings.

Example of my current command line:
"C:\Program Files\Unity\Hub\Editor\2019.2.21f1\Editor\Unity.exe" -quit -batchmode -logFile "%cd%\Build\BuildLog.txt" -projectPath "%cd%\Source\Unity" -executeMethod ProjectName.Builder.Build

Now I have met 2 problems when trying to import the Textmesh Pro package via command line:

1. On the command line manual page, I could not find the correct command to import the package. There is one command seems to be useful: -importPackage <pathname>, but since Textmesh Pro is a Verified package, its source does not stored locally, I can not put something like com.unity.textmeshpro into the <pathname>.
   What is the correct command to import a verified package?
2. Even I can somehow make the command work, Textmesh Pro gives another problem: When being imported, it will open a window with 2 button options. If I don't make the choice during the UI-less build (which I actually can't), the package will simply not be imported and built into the project.
   Is there even a command for making such choice?

I wish everyone in our community have a nice holiday and keep healthy!
Cheers

 

The new year vacation is finally over . I hope everyone is still fine!
Can someone help me here?
