MARS Package has invalid dependencies??

Hello, I am a very new AR developer. I am trying to get AR interactive toolkit to work in Unity 2019.3.15 along with MARS, and it was working out sort of but now I have this error now appearing,
“An error occurred while resolving packages:
Package com.unity.mars@1.0.1 has invalid dependencies:
com.unity.timeline: Resolved version [1.2.6] does not satisfy requested version [1.2.10]”

It says I can do manual modification to the json.file and I am wondering what do I modify?

Hello @lauren_moore ,

just update the Timeline Package to 1.2.10. To do so; go to Window → Package Manager and search for Timeline
