react-bootstrap-table: cannot set a glyphicon on a custom toolbar button

Question

I am customizing the toolbar of a table, following this example: http://allenfang.github.io/react-bootstrap-table/custom.html#insertBtn

I can see my buttons, but not the icons that I set with btnGlyphicon.

The generated html is <i class="fa glyphicon glyphicon-edit"></i> Are both fa + glyphicon expected in the class ? I added font-awesome as a dependency, but I still cannot see the icon.

What am I missing?

Any help appreciated

import React from 'react';

import {
	BootstrapTable, TableHeaderColumn, 
	ButtonGroup, Button, InsertButton
} from 'react-bootstrap-table';
import './../node_modules/react-bootstrap-table/dist/react-bootstrap-table-all.min.css';
import './../node_modules/bootstrap/dist/css/bootstrap.min.css';


createCustomButtonGroup(props) {
		return (
		  <ButtonGroup className='my-custom-class' sizeClass='btn-group-md'>
			{ props.exportCSVBtn }
			<InsertButton 
			  btnText='Info'
			  className='my-custom-class'
			  btnGlyphicon='glyphicon-edit'
			  onClick={ () => this.changeInfoFilter() }/>
			<InsertButton 
			  btnText='Warning'
			  className='my-custom-class'
			  btnGlyphicon='glyphicon-edit'
			  onClick={ () => this.changeWarningFilter() }/>
			<InsertButton
			  btnText='Error'
			  className='my-custom-class'
			  btnGlyphicon='glyphicon-edit'
			  onClick={ () => this.changeErrorFilter() }/>
			<InsertButton 
			  btnText='Command'
			  className='my-custom-class'
			  btnGlyphicon='glyphicon-edit'
			  onClick={ () => this.changeCommandFilter() }/>
		  </ButtonGroup>
		);
	}

Apparently it is a known issue, glyphicons are not in bootstrap 4: https://getbootstrap.com/docs/4.0/migration/
