Browser api problem because of manifest version

[erensertkaya]

I am building an extension that needs to know if certain request are done in a certain pages, because i am trying to scrapping information from spa via content script. For this purpose i decided to use webRequest api but it didn't work since i am building my extension into chrome-v3 which is default and webRequest api only support mv2, then i find declarativeNetRequest api but it didn't provide what i want in the first place. I look to plasmo docs then i find that i can't build my extension into mv2. Do you know any workaround or any other api that can't provide my request in the first sentence ?
