I'd suggest a few steps:

1. try running the same step after a few seconds (sometimes 2s is not enough to element to load)
2. check if you are interacting with the correct window/tab
3. verify if there are no "spaces" in the text try using contain: bot.FindElementByXPath("//div[contains(text(), 'IMECall')]").Click
4. check for iframes (I had many problems with that when I was learning to use selenium with vba) check if there is a tag "iframe" in devtools. if the element is inside a frame:

bot.SwitchToFrame bot.FindElementByTag("iframe")

bot.FindElementByXPath("//div[text()='IMECall']").Click

bot.SwitchToDefaultContent ' Return to the main page

there are other steps, but those would be my first guesses
