I previously developed a function in odoo 14 to select the saved draft for the new form record, but when I migrated it to odoo 16, these functions (updateControlPanel() and _setMode('edit')) could not be called. Can someone tell me how to refresh the field values ​​on the form page in odoo 16? As you can see I've already created a handle for the record. Here's my code below:

patch(FormController.prototype, "BaseDraftController", {
async _createRecord(draft_id,form_json,initialState_context, parentID =undefined, additionalContext=undefined) {
    const record = this.model.__bm__.get(this.model.root.__bm_handle__, { raw: true });
    var context_ = record.getContext({ additionalContext: undefined});
    var _context ={};
    var __context ={};
    _.forEach(context_, function(v, i) {
        _context[i] = v;
        __context[i] = v;
    })
    var _json = eval('('+form_json+')');
    delete _json.message_main_attachment_id;
    _json["base_draft_id"]= draft_id
    _context["default__initialState_context"] = initialState_context;
    _.forEach(_json, function(v, i) {
        if(record.fields[i].type=='many2one' || record.fields[i].type=='one2many'){
            if(typeof v == 'object' && v.length ==2){
                if(v[0] !=null){
                    _context["default_"+i] = v[0];
                }else{
                    delete _json[i];
                }
            }
        } else {
            _context["default_"+i] = v;
        }
    })
    _context["default__all"] = _json;
    const handle = await this.model.__bm__.load({
        context: _context,
        fields: record.fields,
        fieldsInfo: record.fieldsInfo,
        modelName: this.model_name,
        parentID: parentID,
        res_ids: record.res_ids,
        type: 'record',
        viewType: 'form',
    });
    this.model.__bm__.handle = handle;
	​ // TypeError: this.updateControlPanel is not a function
    this.updateControlPanel();
    this._setMode('edit');
    this.model.__bm__.localData[this.model.root.__bm_handle__].context=__context
},
)}

Thank you!
