I need a 2 female TRRS to 1 male TRRS 3.5mm splitter (self.headphones)

I am trying to use a lav mic with my headphones cause the inline mic for them broke. The headphones only have a TRRS output and the mic has a TRRS with a TRS converter/adapter. Can I find a 2 female TRRS and TRS to 1 male TRRS 3.5mm adapter? Would a 2 TRS female to 1 TRRS male adapter work in this scenario even tho my headphones are TRRS only? I know the mic sleeve is the end ring so maybe I dont need to fully plug in the headphones cause I'm trying to use another mic anyway.

These are the three things I have found -

Lav mic - https://www.amazon.in/Maono-AU-400-Lavalier-Microphone-Black/dp/B07JF9B592

Splitter(jack type unknown. possible 2 female TRS to 1 male TRRS) - https://www.amazon.in/Kinsound-Male-Female-Smartphone-Laptop（Grey）/dp/B089NVPFYY

Splitter(apparently 2 female TRRS to 1 male TRRS. practically perfect for my purpose) - https://www.amazon.in/CABLESETC-Universal-Microphone-Duplicator-Splitter/dp/B01MXPFQ85

I am not an avid electrical engineering guy. Just trying to fix some stuff with the limited knowledge I have.

I am making assumptions about the layout of your TRRS plugs, so it may still not work... be warned.

Your best bet here is to buy a dual TRS female to single TRRS male, specifically one with labeled headphone and mic inputs. The TRRS male from your headphones will have the second ring, the headset mic (TRRS), shorted to ground (S) when plugged into the headphone side of the adapter.

For the lav mic, the TRRS male layout is harder to predict, so using the included TRRS female to TRS male barrel adapter and plugging it into the mic-side of the dual-female-single-male adapter.

The expected behavior would be your headset and lav mic behaving like mic-less headphones and a TRS mic, consolidated into one TRRS male plug as a "headset." This is jank, but is a setup I have used myself. Ideally, you'd be able to buy a TRRS to TRS adapter for the lav mic separately, as those barrel adapters really suck and break too easily.

Is there any reason that the dual TRRS to single TRRS wouldnt work? Its the third link. It says that it's used for splitting one jack to be used by two headphones. Would the mic not function in this case?

I didn't suggest it because I have no clue how the adapter you linked would handle and combine two mic signals, and if it does, it would be combining the lav mic signal with your broken headset mic signal which could become frustrating (say, if your broken headset mic desides to start making static noise).

Hmm I see. Currently the headset mic doesn't input anything. I think I'll just buy both adapters and check it out.
