How to remove Bolt from Unity 2019.4.16f1

I would like to remove Bolt from Unity. But I can’t find “remove” button next to Bolt in Package Manager. I need to remove it to make the update of Bolt. There is no Bolt in “In Project” category nor “Built-in packages”. It only exists in “My Assets”
Here is a picture that shows missing option to remove:

to remove bolt, Go into your project file (the file of the project you want to remove bolt from), find assets. delete both the folder and the meta file named bolt.

bump,

I would also like to know… It’s not in the plugin’s folder either. I can’t find where this plugin lives after it was installed.

Did anyone figure it out after all this time?
