For selecting multiple columns, I attempted to press the ctrl button using WebDriverIO - 8 and node 16. However, despite trying various methods such as using await browser.keys(Key.Control), ctrl functionality was not achieved.
await browser.keys(Key.Control);
await campaignNameColumn.click();
await browser.keys(Key.Control);
await monthColumn.click();
I also experimented with different actions but have not had any success so far.
