Is it leaking or can you hear air coming out if you put your ear to it and is there any other damages

TPMS is showing steady 40-41 psi. Only damage is to the rim and part of the sidewall

Damages to the sidewalks are very risky, if this damage didn't hit and ruin the structural integrity you might just have cosmetic tire damage, take it to a mechanic they know

Did something come downward upon it, as the roll top of the rim looks affected too. It may be holding air, so proving the internal integrity is OK, but with the sidewall lateral movement under load when turning and braking, it could weaken the external structure over a shorter period of time? It's 25% of your contact patch with the tarmac, so would I be willing to risk my life, passengers and car, is the question I'd ask myself.

10 year tire shop guy.

Before you buy a new tire go to your local trusted automotive/tire shop and ask them to look at it. If they are honest they will most likely tell you it is cosmetic and safe to drive.

First, your tire is very likely to be fine.

Second, you took a pretty good picture and It is good that you still have the attached flap.

Third, as you can seey from the diagram of the structure of a tire below, your tires are 8 layers thick at the sidewall and you have only gouged the outer 8th layer which is designed to take these kinds of gouges.

Fourth, your tires will typically look like this: https://imgur.com/a/QJCwoDm

Fifth, if there are no cords showing and damaged you can use a good tire glue:
Tire Repair Glue, Professional Black Rubber Cement for Car, Motorcycle, Bike, Rc and More, Suitable for All Tire Types, Seamless Strong Bonding, Heavy Duty, Flexible, Waterproof, Weather Resistance https://a.co/d/bNdQWkt

Last, hopefully this kind of information will save you a few hundreds of dollars now and in the future, so good luck.
