How to use the @typescript-eslint/eslint-plugin/dist/util.getNameFromClassMember function in @typescript-eslint/eslint-plugin

function checkMethodAccessibilityModifier(methodDefinition) {
      let nodeType = 'method definition'

      if (['get', 'set'].includes(methodDefinition.kind)) {
        nodeType = `${methodDefinition.kind} property accessor`
      }

      if (isTypeScriptFile(context.getFilename())) {
        const methodName = util.getNameFromClassMember(methodDefinition, sourceCode)

        if (!!methodDefinition.accessibility) {
          reportIssue('presentModifier', nodeType, methodDefinition, methodName)
        }
      }
    }
