well, ya gotta open it up eventually. If you dont want to vent, you can filter - lots of grow tents come with big carbon packs to keep the pot smell down for pot growers. Those would pull 90% of the fumes from the air, but you will eventually spend the carbon. I have no experience with them, but if they have a pound or two of carbon in them, should last a long time. I am ignorant on them, and an issue could be if they add too much back pressure to a small fan, it may not be effective (like the 120mm one I linked). You may have to use an inline fan (target cfm at 80+CFM), but those are sort of loud.
I have no idea what product this is but scroll through the pictures for different examples of ways to set up filter and fan https://www.amazon.com.au/Vanleno-Australia-Charcoal-Prefilter-Hydroponics/dp/B085DMC2LX

No problem this one is great
Oh no, these are not going to help your smell all that much . These are filters for intake ... a carbon filter like these are the standard for growing. https://www.amazon.com/dp/B085DMC2LX/ref=cm_sw_r_cp_apa_fabc_ObxVFbCY25Q35
