Need to update table asynchronously with data from api Reactjs

I am trying to fetch data from the db asynchronously whenever a new field is updated but even after adding the necessary async and await keyword the table gets updated only on page load.

I have a form to submit data to the db and i want the table to be updated as soon as it happens

Code to update table

const entryList = []
const [tableEntries, setTableEntries] = React.useState(entryList)

useEffect(() => {
async function fetchMyAPI() {
await Axios.get('http://localhost:8080/api/connections')
 .then(res => {
  const newList =  entryList.concat(res.data);
  Array.prototype.forEach.call(newList, response => {
    setTableEntries(prevTableEntries => [...prevTableEntries,response]);
  });
 })
 .catch(err => console.log(err));
}

fetchMyAPI()

}, []);

Code to display data inside of the table

{ tableEntries.map((item) => (
              <>
              <tr>
              <th scope="row">1</th>
              <td>{item.id}</td>
              <td>{item.name}</td>
              <td>{item.connectionType}</td>
              <td>
                <CDropdown className="m-1" size="lg">
                  <CDropdownToggle color="secondary">
                    Select Option
                  </CDropdownToggle>
                  <CDropdownMenu>
                    <CDropdownItem>Delete</CDropdownItem>
                    <CDropdownItem>Reauthorize</CDropdownItem>
                  </CDropdownMenu>
                </CDropdown>
              </td>
              </tr>
              </>
            ))}

Code for form submission (Including this incase this was necessary for you guys to understand)

async handleSubmit(event) {
    event.preventDefault(); // stop browser from submitting form
    const form = await event.target; // get form element
    const article = { "connectionType": "InstagramConnection", "name": this.state.value, "accessCredentials": { "id": 2, "token": this.state.access_token } };
    await Axios.post('http://localhost:8080/api/connections', article)
    .then(response => console.log(response.data))
    .catch(error => {
        console.log('There was an error!', error);
    })
  }

(EDIT: Added the variables which i am using for updating the table to the code able for easier reference)
