New guy to IT team . Need advice

So I work for a non profit health clinic . and we have an MSP , I’m the only IT guy on site 5 days a week traveling to 3-4 different locations. . we have limited funding and everything is hard to get we have to work with what we have mindset even if it’s some what broken , I’m also doing everything from level 1 help desk , troubleshooting all issues and problems , security training phishing test end user training etc , phone system .. anything computer related I’m the only guy even if it’s out my scope … communication is also bad here .. I also guess this company never had an IT guy and people had to wait hours to get password reset which is wild . . With 100 users do u guys think it’s possible to WFH 1-2 days being 2-3 months new to a company .? sometimes its really quiet I drive an hour away and weather is bad how should I phrase or word this to CEO if he let me work from home . can I say like I took care of all the issues on site etc etc idk
