Hi Magdalena, Not much to post really as it is default MDB page modal with an Iframe insert. Basically do not want the modal to scroll at all.

import React, { Component } from "react";

import { MDBBtn, MDBModal, MDBModalBody, MDBModalFooter, MDBRow, MDBIcon, MDBIframe } from "mdbreact";

class IframePage extends Component { state = { modal11: false, }

toggle = nr => () => {
    let modalNumber = "modal" + nr;
    this.setState({
        ...this.state,
        [modalNumber]: !this.state[modalNumber]
    });
}


render() {
    return (
        <MDBRow>
            <MDBBtn onClick={this.toggle(11)}>Launch  Connect</MDBBtn>
            <MDBModal size="md" isOpen={this.state.modal11} toggle={this.toggle(11)}>

                <MDBModalBody className="mb-0 p-0">


                    <MDBIframe allowFullScreen title="connect" src="https://vmixcall.com" >
                        <img src="Vmixcalllogo-300-bl.png" />
                    </MDBIframe>
                </MDBModalBody>
                <MDBModalFooter className="justify-content-center">

                    <MDBBtn color="primary" outline rounded size="md" className="ml-4" onClick={this.toggle(11)}>
                        Close
      </MDBBtn>
                </MDBModalFooter>
            </MDBModal>
        </MDBRow >
    );
}

}

export default IframePage;
