May I suggest fast file transfer as an alternative to apps like SHAREit. It has just a tiny banner ad right at the bottom, allows turning off telemetry and offers a one time IAP pro version that turns off ads and allows to receive files from users without the app installed and from PC and its pretty fast.
A bonus is that the app dev responds pretty quickly to an issues that you may have. It's an awesome app that I feel sadly not a lot of people know about .
Have a look at Fast File Transfer, it may be what you're looking for. I used it to transfer some thing to my brothers iPhone once
Edit: something shitty happened and the app 'Fast File Transfer' on the play store isn't the one I was using. It's been removed for some reason, unless you can see this https://play.google.com/store/apps/details?id=com.floriandraschbacher.fastfiletransfer
Edit 2: even stranger, I think it's blocked in my Country since installing it, WTF?
Edit 3: apkmirror can't find it but try this for a mirror.
If possible, I'd recommend something that does WiFi direct file transfers. I use fast file transfer but there are many options.
Otherwise, you'll likely have upload the file to the cloud and access it from there.

There are probably better apps out there, but that has worked well for me.
I use fast file transfer to send things over wifi. Works with computers as well as phones

the receiver doesn't need to have the app installed
Fast File Transfer sounds similar to wifi file transfer
I've used Fast File Transfer but these days usually just ftp or send via ES File Explorer
Another good one is Fast File Transfer although BT Sync is probably faster.
