RTE: Dynamically change selection

[nxvhm]

Hello and thanks for the great editor.

I want to ask is it possible to change selection dynamically. I have a case where I need to modify a link through a dialog, but when clicked on the dialog inputs, the selection is reset and I can't seem to modify it again to be the same.

editor.RichTextEditor.add('my-link', {
    icon: '<i class="fas fa-link"></i>',
    attributes: {title: 'Link'},
    result: rte => {
        window.rte = rte;
        let selection = rte.selection();
                            // save the initial state of the selection
        window.initialSelection = {
            anchorNode: selection.anchorNode,
            anchorOffset: selection.anchorOffset,
            focusNode: selection.focusNode,
            focusOffset: selection.focusOffset,
            rangeCount: selection.rangeCount,
            type: selection.type,
        };
        openLinkModal(rte.selection());
        return false;
}

And then when I have to insert the link:

let addLink = () => {

    let linkValue = $('#linkValue').val();
    let linkText = $('#linkText').val();
    
    let selection = window.rte.selection();

    // Set the selection state to the initial one ? 
    selection.focusNode = window.initialSelection.focusNode;
    selection.anchorOffset = window.initialSelection.anchorOffset;
    selection.focusOffset =  window.initialSelection.anchorOffset;
    selection.rangeCount = window.initialSelection.rangeCount;
    selection.type = window.initialSelection.type;

    window.rte.insertHTML(`<a href="${linkValue}">${selection}</a>`)
    $('#linkModal').modal('hide');
}

Is there an API or something with which I can set the selection's focusNode, offsets, etc. since I can't seem to find one and the above is not working ?
