How to create an Element Room with configurations suited for my less techy family?

Could someone recommend how I could create a private Element room with settings that make it easier for my family members with less technical experiences to chat in while ensuring privacy, for example, disabling E2E & session verification etc. I am also new to this app and don't know the way around it very much so I don't know what things I need to disable/enable that would make chatting in this app as convenient as WhatsApp. Is there some guide to this or can I do this on my own?

For context, I am really a privacy-focused person and tend to use privacy friendly applications and alternatives, even to the point of tolerating inconveniences of these apps due to them being privacy-oriented, however I cannot say the same about my family. Rest assured I am not a suspect who would have their devices scanned by the police nor am I planning to do something illegal that would require me to enable all the security and privacy features of the apps just to casually chat with my family.
