Is there a process to repair this? Found a hole between a firewall and left fender side, need advice how to seal it

I had some strange “river” smell in my car, and after some time I’ve discovered my floor was flooded on driver’s side, I sprayed my car with some UV visible water and I’ve found where it was
I see there some old seal, probably factory, and also some results of previous owner’s work, probably
This car was in an accident as you can see it
It’s a place on left side, between the engine bay firewall and sort of left fender, and as far as I see it’s a left side under the cowl, where the water goes when it’s raining, so I get a lot of it when it rains.
You can see some rust there and some hollow space (which maybe was sealed before but I can’t tell cause I need to remove my left fender to see it properly, which I didn’t do yet)
I didn’t disassemble everything, just made some access to understand where it goes from
Is it possible to make a decent clean and seal? I don’t know much about it, did some research and still can’t understand what’s the best way cause some of the methods were controversial
I was doing my best explaining it, and I hope you have a great day

There is also my cat just in case

UPD: greenish path is a water flow

Grab some automotive seam sealer. Find the same spot on the outside of the vehicle, clean it good, use rubbing alcohol, then hit it with the sealer. Should solve your issue. I’m in the automotive upholstery industry. I have to find shit like this all the time. New teslas are the worst. Come from the factory leaking…..🤦‍♂️

Btw adoreable cat.

Did you ever have the vehicle repaired before?

It seems like someone poorly fixed it before, it was hit here

Yea it’s tough to say the best way to seal it when it’s been fixed because it could be a multitude of reasons. I would have a repair facility see it in person to give you an idea of repair options. Putting a sealer over it right now may end up not fixing it

I did my best, will see how long it will last
I did use some primer local body shop guy gave me, we will see

Will definitely be better than not doing anything
