node >= 10.18 is necessary ?

[whatwg6]

Problem

• Node version in my CI runner was 10.15.3.
• When CI install react-tooltip will throw error [email protected]: The engine "node" is incompatible with this module. Expected version ">=10.18". Got "10.15.3"

So

• does node >= 10.18 is really necessary ?
• react-tooltip package depends on node >=10.18 ?

package.json

"engines": {
    "node": ">=10.18",
    "npm": ">=6.13"
  },
