Mount inquiry

Hello, need help with mounting.

I want to mount my Insta360 invisible stick onto the car. How do I get it to stay solid?

Trying to install it sideways, not front or back but on the side of the car - Pointing outwards and up, to the left. (Driver side).

Which mount base do I use to keep things stable and secure?

What do people recommend?

Original plan is to be driving around 60-80km/h to take some shots.
Roughly will be driving up to 100-110km/h if using the free-way/high-way -- but I can avoid this if the speed is not supported by mounts.

What mounts do people recommend? Adhesive? Suction? Magnet? Can you give me some links to mounts?

I would really appreciate it.

Thank you.
