Thunderbird – Have 2 gmail accounts – want to see each calendar independent of the other

Our company has just switched from exchange to GSuite. I already have my personal email and calendar and I use Thunderbird. I added my work email to Thunderbird. I would like to be able to open calendar and either have it show my work calendar OR my personal calendar – but NOT both merged. I cannot seem to figure out how to do this. It seems to be one and all has to be on that one – as opposed to mail where it shows me my 2 email accounts and I can open whichever one for whom I want to see the email.
