And if you can bend from the waist and extend your leg straight back here is another option.
Standing on the left side of the bike, grab the right handlebar in your right hand and lean the bike to the left, as far down as your arm will allow. That will put the bike leaning close to the ground with the top tube and seat at about knee level.
Bend forward from the waist and extend your leg straight back, reaching as high as possible. Hopefully, you can get your leg and upper body parallel to the ground. Your leg is now clear of the seat and top tube since they are at about knee level.
All it takes is a small pivot to swing your leg over the seat/top tube. Then bring the bike back to an upright position, and you're off.
I have limited range of motion due to rheumatoid arthritis, and that trick has worked for me for the last several years.
Hope you find something that works for you
